9# From Paul Eggert (2013-08-11):
10#
11# A good source for time zone historical data outside the U.S. is
12# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
13# San Diego: ACS Publications, Inc. (2003).
14#
15# Gwillim Law writes that a good source
16# for recent time zone data is the International Air Transport
17# Association's Standard Schedules Information Manual (IATA SSIM),
18# published semiannually. Law sent in several helpful summaries
19# of the IATA's data after 1990.
20#
21# Except where otherwise noted, Shanks & Pottenger is the source for
22# entries through 1990, and IATA SSIM is the source for entries afterwards.
23#
24# Another source occasionally used is Edward W. Whitman, World Time Differences,
25# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
26# I found in the UCLA library.
27#
28# For data circa 1899, a common source is:
29# Milne J. Civil time. Geogr J. 1899 Feb;13(2):173-94
30# <http://www.jstor.org/stable/1774359>.
31#
32# A reliable and entertaining source about time zones is
33# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).

90# Armenia
91# From Paul Eggert (2006-03-22):
92# Shanks & Pottenger have Yerevan switching to 3:00 (with Russian DST)
93# in spring 1991, then to 4:00 with no DST in fall 1995, then
94# readopting Russian DST in 1997. Go with Shanks & Pottenger, even
95# when they disagree with others. Edgar Der-Danieliantz
96# reported (1996-05-04) that Yerevan probably wouldn't use DST
97# in 1996, though it did use DST in 1995. IATA SSIM (1991/1998) reports that
98# Armenia switched from 3:00 to 4:00 in 1998 and observed DST after 1991,
99# but started switching at 3:00s in 1998.
100
101# From Arthur David Olson (2011-06-15):
102# While Russia abandoned DST in 2011, Armenia may choose to
103# follow Russia's "old" rules.

306# From Guy Harris:
307# People's Republic of China. Yes, they really have only one time zone.
308
309# From Bob Devine (1988-01-28):
310# No they don't. See TIME mag, 1986-02-17 p.52. Even though
311# China is across 4 physical time zones, before Feb 1, 1986 only the
312# Peking (Bejing) time zone was recognized. Since that date, China
313# has two of 'em -- Peking's and Urumqi (named after the capital of
314# the Xinjiang Uyghur Autonomous Region). I don't know about DST for it.
315#
316# . . .I just deleted the DST table and this editor makes it too
317# painful to suck in another copy.. So, here is what I have for
318# DST start/end dates for Peking's time zone (info from AP):

347# Chinese names for these locales (before 1949).
348#
349# From Jesper Norgaard Welen (2006-07-14):
350# I have investigated the timezones around 1970 on the
351# http://www.astro.com/atlas site [with provinces and county
352# boundaries summarized below].... A few other exceptions were two
353# counties on the Sichuan side of the Xizang-Sichuan border,
354# counties Dege and Baiyu which lies on the Sichuan side and are
355# therefore supposed to be GMT+7, Xizang region being GMT+6, but Dege
356# county is GMT+8 according to astro.com while Baiyu county is GMT+6
357# (could be true), for the moment I am assuming that those two
358# counties are mistakes in the astro.com data.
359
360# From Paul Eggert (2008-02-11):
361# I just now checked Google News for western news sources that talk
362# about China's single time zone, and couldn't find anything before 1986
363# talking about China being in one time zone. (That article was: Jim
364# Mann, "A clumsy embrace for another western custom: China on daylight
365# time--sort of", Los Angeles Times, 1986-05-05. By the way, this
366# article confirms the tz database's data claiming that China began
367# observing daylight saving time in 1986.
368#
369# From Thomas S. Mullaney (2008-02-11):
370# I think you're combining two subjects that need to treated
371# separately: daylight savings (which, you're correct, wasn't
372# implemented until the 1980s) and the unified time zone centered near
373# Beijing (which was implemented in 1949). Briefly, there was also a
374# "Lhasa Time" in Tibet and "Urumqi Time" in Xinjiang. The first was
375# ceased, and the second eventually recognized (again, in the 1980s).
376#
377# From Paul Eggert (2008-06-30):
378# There seems to be a good chance China switched to a single time zone in 1949
379# rather than in 1980 as Shanks & Pottenger have it, but we don't have a
380# reliable documentary source saying so yet, so for now we still go with

424# From Luther Ma (2009-10-17):
425# Almost all (>99.9%) ethnic Chinese (properly ethnic Han) living in
426# Xinjiang use Chinese Standard Time. Some are aware of Xinjiang time,
427# but have no need of it. All planes, trains, and schools function on
428# what is called "Beijing time." When Han make an appointment in Chinese
429# they implicitly use Beijing time.
430#
431# On the other hand, ethnic Uyghurs, who make up about half the
432# population of Xinjiang, typically use "Xinjiang time" which is two
433# hours behind Beijing time, or UTC +0600. The government of the Xinjiang
434# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as
435# local governments such as the Urumqi city government use both times in
436# publications, referring to what is popularly called Xinjiang time as
437# "Urumqi time." When Uyghurs make an appointment in the Uyghur language
438# they almost invariably use Xinjiang time.
439#
440# (Their ethnic Han compatriots would typically have no clue of its
441# widespread use, however, because so extremely few of them are fluent in
442# Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.)
443#
444# (...As with the rest of China there was a brief interval ending in 1990
445# or 1991 when summer time was in use. The confusion was severe, with
446# the province not having dual times but four times in use at the same
447# time. Some areas remained on standard Xinjiang time or Beijing time and
448# others moving their clocks ahead.)

466# With the risk of being redundant to previous answers these are the most common

468#
469# 1. Wulumuqi...

471# 3. Urumqi...
472# 4. Kashgar...
473# ...
474# 5. It seems that Uyghurs in Urumqi has been using Xinjiang since at least the
475# 1960's. I know of one Han, now over 50, who grew up in the surrounding
476# countryside and used Xinjiang time as a child.
477#
478# 6. Likewise for Kashgar and the rest of south Xinjiang I don't know of any
479# start date for Xinjiang time.
480#
481# Without having access to local historical records, nor the ability to legally
482# publish them, I would go with October 1, 1949, when Xinjiang became the Uyghur
483# Autonomous Region under the PRC. (Before that Uyghurs, of course, would also
484# not be using Beijing time, but some local time.)

792# from JST to UTC+07:30 on 1945-09-23, and gives 1944-09-01 for Jayapura
793# (Hollandia). For now, assume all Indonesian locations other than Jayapura
794# switched on 1945-09-23.
795#
796# From Paul Eggert (2013-08-11):
797# Normally the tz database uses English-language abbreviations, but in
798# Indonesia it's typical to use Indonesian-language abbreviations even
799# when writing in English. For example, see the English-language
800# summary published by the Time and Frequency Laboratory of the
801# Research Center for Calibration, Instrumentation and Metrology,
802# Indonesia, <http://time.kim.lipi.go.id/time-eng.php> (2006-09-29).
803# The abbreviations are:
804#
805# WIB - UTC+7 - Waktu Indonesia Barat (Indonesia western time)
806# WITA - UTC+8 - Waktu Indonesia Tengah (Indonesia central time)
807# WIT - UTC+9 - Waktu Indonesia Timur (Indonesia eastern time)

846# From Roozbeh Pournader (2003-03-15):
847# This is an English translation of what I just found (originally in Persian).
848# The Gregorian dates in brackets are mine:
849#
850# Official Newspaper No. 13548-1370/6/25 [1991-09-16]
851# No. 16760/T233 H 1370/6/10 [1991-09-01]
852#
853# The Rule About Change of the Official Time of the Country
854#
855# The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14],
856# based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13]
857# of the Country's Organization for Official and Employment Affairs,
858# and referring to the law for equating the working hours of workers
859# and officers in the whole country dated 1359/4/23 [1980-07-14], and
860# for synchronizing the official times of the country, agreed that:
861#
862# The official time of the country will should move forward one hour
863# at the 24[:00] hours of the first day of Farvardin and should return
864# to its previous state at the 24[:00] hours of the 30th day of
865# Shahrivar.
866#
867# First Deputy to the President - Hassan Habibi
868#
869# From personal experience, that agrees with what has been followed
870# for at least the last 5 years. Before that, for a few years, the
871# date used was the first Thursday night of Farvardin and the last
872# Thursday night of Shahrivar, but I can't give exact dates....
873# I have also changed the abbreviations to what is considered correct
874# here in Iran, IRST for regular time and IRDT for daylight saving time.
875#
876# From Roozbeh Pournader (2005-04-05):
877# The text of the Iranian law, in effect since 1925, clearly mentions
878# that the true solar year is the measure, and there is no arithmetic
879# leap year calculation involved. There has never been any serious
880# plan to change that law....
881#
882# From Paul Eggert (2006-03-22):
883# Go with Shanks & Pottenger before Sept. 1991, and with Pournader thereafter.
884# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,
885# stopping after 2037 when 32-bit time_t's overflow.
886# That cal-persia used Birashk's approximation, which disagrees with the solar
887# calendar predictions for the year 2025, so I corrected those dates by hand.
888#
889# From Oscar van Vlijmen (2005-03-30), writing about future
890# discrepancies between cal-persia and the Iranian calendar:
891# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
892# the vernal equinox and that gets so close to 12:00 some local
893# Iranian time that the definition of the correct location needs to be
894# known exactly, amongst other factors. 2157 is even closer:
895# 2157-03-20 08:37:15.5 UT. But the Gregorian year 2025 should give
896# no interpretation problem whatsoever. By the way, another instant
897# in the near future where there will be a discrepancy between
898# arithmetical and astronomical Iranian calendars will be in 2058:
899# vernal equinox on 2058-03-20 09:03:05.9 UT. The Java version of
900# Reingold's/Dershowitz' calculator gives correctly the Gregorian date
901# 2058-03-21 for 1 Farvardin 1437 (astronomical).
902#
903# From Steffen Thorsen (2006-03-22):
904# Several of my users have reported that Iran will not observe DST anymore:
905# http://www.irna.ir/en/news/view/line-17/0603193812164948.htm
906#
907# From Reuters (2007-09-16), with a heads-up from Jesper Norgaard Welen:
908# ... the Guardian Council ... approved a law on Sunday to re-introduce
909# daylight saving time ...
910# http://uk.reuters.com/article/oilRpt/idUKBLA65048420070916
911#
912# From Roozbeh Pournader (2007-11-05):
913# This is quoted from Official Gazette of the Islamic Republic of
914# Iran, Volume 63, Number 18242, dated Tuesday 1386/6/24
915# [2007-10-16]. I am doing the best translation I can:...
916# The official time of the country will be moved forward for one hour
917# on the 24 hours of the first day of the month of Farvardin and will
918# be changed back to its previous state on the 24 hours of the

981# From Jonathan Lennox (2000-06-12):
982# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
983# the U.S. edition) on the Iraqi Kurds contains a paragraph:
984# "The three northern provinces ... switched their clocks this spring and
985# are an hour ahead of Baghdad."
986#
987# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
988# In the past, some Kurdish nationalists, as a protest to the Iraqi
989# Government, did not adhere to daylight saving time. They referred
990# to daylight saving as Saddam time. But, as of today, the time zone
991# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
992#
993# So we'll ignore the Economist's claim.

1032
1033# From Ephraim Silverberg (2001-01-11):
1034#
1035# I coined "IST/IDT" circa 1988. Until then there were three
1036# different abbreviations in use:
1037#
1038# JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
1039# IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
1040# EEST Eastern Europe Standard Time [used by almost everyone else]
1041#
1042# Since timezones should be called by country and not capital cities,
1043# I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
1044# EEST was equally unacceptable. Since "zonal" was not compatible with
1045# any other timezone abbreviation, I felt that 'IST' was the way to go
1046# and, indeed, it has received almost universal acceptance in timezone
1047# settings in Israeli computers.
1048#
1049# In any case, I am happy to share timezone abbreviations with India,
1050# high on my favorite-country list (and not only because my wife's
1051# family is from India).

1096# From Ephraim Silverberg
1097# (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17, 2000-07-25, 2004-12-22,
1098# and 2005-02-17):
1099
1100# According to the Office of the Secretary General of the Ministry of
1101# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
1102# One thing is entrenched in law, however: that there must be at least 150
1103# days of daylight savings time annually. From 1993-1998, the change to
1104# daylight savings time was on a Friday morning from midnight IST to
1105# 1 a.m IDT; up until 1998, the change back to standard time was on a
1106# Saturday night from midnight daylight savings time to 11 p.m. standard
1107# time. 1996 is an exception to this rule where the change back to standard
1108# time took place on Sunday night instead of Saturday night to avoid
1109# conflicts with the Jewish New Year. In 1999, the change to
1110# daylight savings time was still on a Friday morning but from
1111# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
1112# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
1113# 1999 only. In the year 2000, the change to daylight savings time was
1114# similar to 1999, but although the change back will be on a Friday, it
1115# will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
1116# changes to/from will take place at 1 a.m. old time, but now there is no
1117# rule as to what day of the week it will take place in as the start date
1118# (except in 2003) is the night after the Passover Seder (i.e. the eve
1119# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
1120# (except in 2002) is three nights before Yom Kippur [Day of Atonement]

1257
1258# From Paul Eggert (1995-03-06):
1259# Today's _Asahi Evening News_ (page 4) reports that Japan had
1260# daylight saving between 1948 and 1951, but ``the system was discontinued
1261# because the public believed it would lead to longer working hours.''
1262
1263# From Mayumi Negishi in the 2005-08-10 Japan Times
1264# <http://www.japantimes.co.jp/cgi-bin/getarticle.pl5?nn20050810f2.htm>:
1265# Occupation authorities imposed daylight-saving time on Japan on
1266# [1948-05-01].... But lack of prior debate and the execution of
1267# daylight-saving time just three days after the bill was passed generated
1268# deep hatred of the concept.... The Diet unceremoniously passed a bill to
1269# dump the unpopular system in October 1951, less than a month after the San
1270# Francisco Peace Treaty was signed. (A government poll in 1951 showed 53%
1271# of the Japanese wanted to scrap daylight-saving time, as opposed to 30% who
1272# wanted to keep it.)
1273
1274# From Paul Eggert (2006-03-22):

1281# but the only locations using it (for birth certificates, presumably, since
1282# their audience is astrologers) were US military bases. For now, assume
1283# that for most purposes daylight-saving time was observed; otherwise, what
1284# would have been the point of the 1951 poll?
1285
1286# From Hideyuki Suzuki (1998-11-09):
1287# 'Tokyo' usually stands for the former location of Tokyo Astronomical
1288# Observatory: E 139 44' 40".90 (9h 18m 58s.727), N 35 39' 16".0.
1289# This data is from 'Rika Nenpyou (Chronological Scientific Tables) 1996'
1290# edited by National Astronomical Observatory of Japan....
1291# JST (Japan Standard Time) has been used since 1888-01-01 00:00 (JST).
1292# The law is enacted on 1886-07-07.
1293
1294# From Hideyuki Suzuki (1998-11-16):
1295# The ordinance No. 51 (1886) established "standard time" in Japan,
1296# which stands for the time on E 135 degree.
1297# In the ordinance No. 167 (1895), "standard time" was renamed to "central
1298# standard time". And the same ordinance also established "western standard
1299# time", which stands for the time on E 120 degree.... But "western standard
1300# time" was abolished in the ordinance No. 529 (1937). In the ordinance No.
1301# 167, there is no mention regarding for what place western standard time is
1302# standard....
1303#
1304# I wrote "ordinance" above, but I don't know how to translate.
1305# In Japanese it's "chokurei", which means ordinance from emperor.
1306
1307# Shanks & Pottenger claim JST in use since 1896, and that a few
1308# places (e.g. Ishigaki) use +0800; go with Suzuki. Guess that all

1701
1702# From Paul Eggert (1999-12-15):
1703# Naming and spelling is tricky in Mongolia.

1844# I have been advised that Pakistan has decided to adopt dst on a
1845# TRIAL basis for one year, starting 00:01 local time on April 7, 2002
1846# and ending at 00:01 local time October 6, 2002. This is what I was
1847# told, but I believe that the actual time of change may be 00:00; the
1848# 00:01 was to make it clear which day it was on.

1852# http://www.pak.gov.pk/public/news/app/app06_dec.htm
1853# (dated 2001-12-06) which says that the Cabinet adopted a scheme "to
1854# advance the clocks by one hour on the night between the first
1855# Saturday and Sunday of April and revert to the original position on
1856# 15th October each year". This agrees with McDow's 04-07 at 00:00,
1857# but disagrees about the October transition, and makes it sound like
1858# it's not on a trial basis. Also, the "between the first Saturday

2032# Palestine
2033
2034# From Amos Shapir (1998-02-15):
2035#
2036# From 1917 until 1948-05-15, all of Palestine, including the parts now
2037# known as the Gaza Strip and the West Bank, was under British rule.
2038# Therefore the rules given for Israel for that period, apply there too...
2039#
2040# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
2041# (except a short occupation by Israel from 1956-11 till 1957-03, but no
2042# time zone was affected then). It was never formally annexed to Egypt,
2043# though.
2044#
2045# The rest of Palestine was under Jordanian rule at that time, formally
2046# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
2047# the country's previous name of "the Hashemite Kingdom of the
2048# Trans-Jordan"). So the rules for Jordan for that time apply. Major
2049# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
2050# East Jerusalem.
2051#
2052# Both areas were occupied by Israel in June 1967, but not annexed (except
2053# for East Jerusalem). They were on Israel time since then; there might
2054# have been a Military Governor's order about time zones, but I'm not aware
2055# of any (such orders may have been issued semi-annually whenever summer
2056# time was in effect, but maybe the legal aspect of time was just neglected).
2057#
2058# The Palestinian Authority was established in 1993, and got hold of most
2059# towns in the West Bank and Gaza by 1995. I know that in order to
2060# demonstrate...independence, they have been switching to
2061# summer time and back on a different schedule than Israel's, but I don't
2062# know when this was started, or what algorithm is used (most likely the
2063# Jordanian one).
2064#
2065# To summarize, the table should probably look something like that:
2066#
2067# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
2068# ------------+-----------+-----------+-----------+-----------
2069# Israel | Zion | Zion | Zion | Zion
2070# West bank | Zion | Jordan | Zion | Jordan
2071# Gaza | Zion | Egypt | Zion | Jordan
2072#
2073# I guess more info may be available from the PA's web page (if/when they
2074# have one).
2075
2076# From Paul Eggert (2006-03-22):
2077# Shanks & Pottenger write that Gaza did not observe DST until 1957, but go
2078# with Shapir and assume that it observed DST from 1940 through 1947,
2079# and that it used Jordanian rules starting in 1996.
2080# We don't yet need a separate entry for the West Bank, since
2081# the only differences between it and Gaza that we know about
2082# occurred before our cutoff date of 1970.
2083# However, as we get more information, we may need to add entries
2084# for parts of the West Bank as they transitioned from Israel's rules
2085# to Palestine's rules.
2086
2087# From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time,
2088# forwarded by Ephraim Silverberg:
2089#
2090# Despite the fact that Israel changed over to daylight savings time
2091# last week, the PLO Authority (PA) has decided not to turn its clocks
2092# one-hour forward at this time. As a sign of independence from Israeli rule,
2093# the PA has decided to implement DST in April.

2476# [The Tamil Tigers] never accepted the original 1996 time change and simply

2478# Time (GMT), in line with neighbor India.
2479# From Paul Eggert (2006-04-18):
2480# People who live in regions under Tamil control can use [TZ='Asia/Kolkata'],
2481# as that zone has agreed with the Tamil areas since our cutoff date of 1970.
2482
2483# From K Sethu (2006-04-25):
2484# I think the abbreviation LKT originated from the world of computers at
2485# the time of or subsequent to the time zone changes by SL Government
2486# twice in 1996 and probably SL Government or its standardization
2487# agencies never declared an abbreviation as a national standard.
2488#
2489# I recollect before the recent change the government annoucemments
2490# mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka
2491# Time and no mention was made about the abbreviation.
2492#
2493# If we look at Sri Lanka Department of Government's "Official News
2494# Website of Sri Lanka" ... http://www.news.lk/ we can see that they
2495# use SLT as abbreviation in time stamp at the beginning of each news
2496# item....
2497#
2498# Within Sri Lanka I think LKT is well known among computer users and
2499# adminsitrators. In my opinion SLT may not be a good choice because the
2500# nation's largest telcom / internet operator Sri Lanka Telcom is well
2501# known by that abbreviation - simply as SLT (there IP domains are
2502# slt.lk and sltnet.lk).
2503#
2504# But if indeed our government has adopted SLT as standard abbreviation
2505# (that we have not known so far) then it is better that it be used for
2506# all computers.
2507
2508# From Paul Eggert (2006-04-25):

162# "... Bangladesh government has decided to switch daylight saving time from
163# June
164# 16 till September 30 in a bid to ensure maximum use of daylight to cope with
165# crippling power crisis. "
166#
167# The switch will remain in effect from June 16 to Sept 30 (2009) but if
168# implemented the next year, it will come in force from April 1, 2010
169
170# From Steffen Thorsen (2009-06-02):
171# They have finally decided now, but changed the start date to midnight between

309# From Bob Devine (1988-01-28):
310# No they don't. See TIME mag, 1986-02-17 p.52. Even though
311# China is across 4 physical time zones, before Feb 1, 1986 only the
312# Peking (Bejing) time zone was recognized. Since that date, China
313# has two of 'em -- Peking's and Urumqi (named after the capital of
314# the Xinjiang Uyghur Autonomous Region). I don't know about DST for it.
315#
316# . . .I just deleted the DST table and this editor makes it too
317# painful to suck in another copy.. So, here is what I have for

348#
349# From Jesper Norgaard Welen (2006-07-14):
350# I have investigated the timezones around 1970 on the
351# http://www.astro.com/atlas site [with provinces and county
352# boundaries summarized below].... A few other exceptions were two
353# counties on the Sichuan side of the Xizang-Sichuan border,
354# counties Dege and Baiyu which lies on the Sichuan side and are

359
360# From Paul Eggert (2008-02-11):
361# I just now checked Google News for western news sources that talk

363# talking about China being in one time zone. (That article was: Jim
364# Mann, "A clumsy embrace for another western custom: China on daylight
365# time--sort of", Los Angeles Times, 1986-05-05. By the way, this
366# article confirms the tz database's data claiming that China began
367# observing daylight saving time in 1986.
368#
369# From Thomas S. Mullaney (2008-02-11):
370# I think you're combining two subjects that need to treated
371# separately: daylight savings (which, you're correct, wasn't
372# implemented until the 1980s) and the unified time zone centered near
373# Beijing (which was implemented in 1949). Briefly, there was also a
374# "Lhasa Time" in Tibet and "Urumqi Time" in Xinjiang. The first was

376#
377# From Paul Eggert (2008-06-30):
378# There seems to be a good chance China switched to a single time zone in 1949

424# From Luther Ma (2009-10-17):
425# Almost all (>99.9%) ethnic Chinese (properly ethnic Han) living in
426# Xinjiang use Chinese Standard Time. Some are aware of Xinjiang time,
427# but have no need of it. All planes, trains, and schools function on
428# what is called "Beijing time." When Han make an appointment in Chinese
429# they implicitly use Beijing time.
430#
431# On the other hand, ethnic Uyghurs, who make up about half the
432# population of Xinjiang, typically use "Xinjiang time" which is two
433# hours behind Beijing time, or UTC +0600. The government of the Xinjiang
434# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as
435# local governments such as the Urumqi city government use both times in
436# publications, referring to what is popularly called Xinjiang time as
437# "Urumqi time." When Uyghurs make an appointment in the Uyghur language
438# they almost invariably use Xinjiang time.
439#
440# (Their ethnic Han compatriots would typically have no clue of its
441# widespread use, however, because so extremely few of them are fluent in
442# Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.)
443#
444# (...As with the rest of China there was a brief interval ending in 1990
445# or 1991 when summer time was in use. The confusion was severe, with
446# the province not having dual times but four times in use at the same
447# time. Some areas remained on standard Xinjiang time or Beijing time and
448# others moving their clocks ahead.)

684# From Paul Eggert (1994-11-19):

686# an hour recently, due to a law proposed by Zurab Murvanidze,
687# an MP who went on a hunger strike for 11 days to force discussion about it!
688# We have no details, but we'll guess they didn't move the clocks back in fall.
689#
690# From Mathew Englander, quoting AP (1996-10-23 13:05-04):
691# Instead of putting back clocks at the end of October, Georgia
692# will stay on daylight savings time this winter to save energy,
693# President Eduard Shevardnadze decreed Wednesday.
694#
695# From the BBC via Joseph S. Myers (2004-06-27):
696#
697# Georgia moved closer to Western Europe on Sunday... The former Soviet
698# republic has changed its time zone back to that of Moscow. As a result it
699# is now just four hours ahead of Greenwich Mean Time, rather than five hours
700# ahead. The switch was decreed by the pro-Western president of Georgia,
701# Mikhail Saakashvili, who said the change was partly prompted by the process
702# of integration into Europe.
703
704# From Teimuraz Abashidze (2005-11-07):
705# Government of Georgia ... decided to NOT CHANGE daylight savings time on
706# [Oct.] 30, as it was done before during last more than 10 years.
707# Currently, we are in fact GMT +4:00, as before 30 October it was GMT
708# +3:00.... The problem is, there is NO FORMAL LAW or governmental document
709# about it. As far as I can find, I was told, that there is no document,
710# because we just DIDN'T ISSUE document about switching to winter time....
711# I don't know what can be done, especially knowing that some years ago our
712# DST rules where changed THREE TIMES during one month.

778# <http://www.sumatera-inc.com/go_to_invest/about_indonesia.asp#standtime>
779# says that Indonesia's time zones changed on 1988-01-01. Looking at some

782#
783# From Paul Eggert (2007-03-10):
784# Here is another correction to Shanks & Pottenger.
785# JohnTWB writes that Japanese forces did not surrender control in
786# Indonesia until 1945-09-01 00:00 at the earliest (in Jakarta) and
787# other formal surrender ceremonies were September 9, 11, and 13, plus

789# These would be the earliest possible times for a change.
790# Regimes horaires pour le monde entier, by Henri Le Corre, (Editions

793# (Hollandia). For now, assume all Indonesian locations other than Jayapura

846# From Roozbeh Pournader (2003-03-15):
847# This is an English translation of what I just found (originally in Persian).
848# The Gregorian dates in brackets are mine:
849#
850# Official Newspaper No. 13548-1370/6/25 [1991-09-16]
851# No. 16760/T233 H 1370/6/10 [1991-09-01]
852#
853# The Rule About Change of the Official Time of the Country
854#
855# The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14],
856# based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13]
857# of the Country's Organization for Official and Employment Affairs,
858# and referring to the law for equating the working hours of workers
859# and officers in the whole country dated 1359/4/23 [1980-07-14], and
860# for synchronizing the official times of the country, agreed that:
861#
862# The official time of the country will should move forward one hour
863# at the 24[:00] hours of the first day of Farvardin and should return
864# to its previous state at the 24[:00] hours of the 30th day of
865# Shahrivar.
866#
867# First Deputy to the President - Hassan Habibi
868#
869# From personal experience, that agrees with what has been followed
870# for at least the last 5 years. Before that, for a few years, the
871# date used was the first Thursday night of Farvardin and the last
872# Thursday night of Shahrivar, but I can't give exact dates....
873# I have also changed the abbreviations to what is considered correct
874# here in Iran, IRST for regular time and IRDT for daylight saving time.
875#
876# From Roozbeh Pournader (2005-04-05):
877# The text of the Iranian law, in effect since 1925, clearly mentions
878# that the true solar year is the measure, and there is no arithmetic
879# leap year calculation involved. There has never been any serious
880# plan to change that law....
881#
882# From Paul Eggert (2006-03-22):
883# Go with Shanks & Pottenger before Sept. 1991, and with Pournader thereafter.
884# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,
885# stopping after 2037 when 32-bit time_t's overflow.
886# That cal-persia used Birashk's approximation, which disagrees with the solar
887# calendar predictions for the year 2025, so I corrected those dates by hand.
888#
889# From Oscar van Vlijmen (2005-03-30), writing about future
890# discrepancies between cal-persia and the Iranian calendar:
891# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
892# the vernal equinox and that gets so close to 12:00 some local
893# Iranian time that the definition of the correct location needs to be
894# known exactly, amongst other factors. 2157 is even closer:
895# 2157-03-20 08:37:15.5 UT. But the Gregorian year 2025 should give
896# no interpretation problem whatsoever. By the way, another instant
897# in the near future where there will be a discrepancy between
898# arithmetical and astronomical Iranian calendars will be in 2058:
899# vernal equinox on 2058-03-20 09:03:05.9 UT. The Java version of
900# Reingold's/Dershowitz' calculator gives correctly the Gregorian date
901# 2058-03-21 for 1 Farvardin 1437 (astronomical).
902#
903# From Steffen Thorsen (2006-03-22):
904# Several of my users have reported that Iran will not observe DST anymore:
905# http://www.irna.ir/en/news/view/line-17/0603193812164948.htm

981# From Jonathan Lennox (2000-06-12):
982# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
983# the U.S. edition) on the Iraqi Kurds contains a paragraph:
984# "The three northern provinces ... switched their clocks this spring and
985# are an hour ahead of Baghdad."
986#
987# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
988# In the past, some Kurdish nationalists, as a protest to the Iraqi
989# Government, did not adhere to daylight saving time. They referred
990# to daylight saving as Saddam time. But, as of today, the time zone
991# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
992#
993# So we'll ignore the Economist's claim.

1033# From Ephraim Silverberg (2001-01-11):
1034#
1035# I coined "IST/IDT" circa 1988. Until then there were three
1036# different abbreviations in use:
1037#
1038# JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
1039# IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
1040# EEST Eastern Europe Standard Time [used by almost everyone else]
1041#
1042# Since timezones should be called by country and not capital cities,
1043# I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
1044# EEST was equally unacceptable. Since "zonal" was not compatible with
1045# any other timezone abbreviation, I felt that 'IST' was the way to go
1046# and, indeed, it has received almost universal acceptance in timezone
1047# settings in Israeli computers.
1048#
1049# In any case, I am happy to share timezone abbreviations with India,
1050# high on my favorite-country list (and not only because my wife's
1051# family is from India).

1096# From Ephraim Silverberg
1097# (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17, 2000-07-25, 2004-12-22,
1098# and 2005-02-17):
1099
1100# According to the Office of the Secretary General of the Ministry of
1101# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
1102# One thing is entrenched in law, however: that there must be at least 150
1103# days of daylight savings time annually. From 1993-1998, the change to
1104# daylight savings time was on a Friday morning from midnight IST to
1105# 1 a.m IDT; up until 1998, the change back to standard time was on a
1106# Saturday night from midnight daylight savings time to 11 p.m. standard
1107# time. 1996 is an exception to this rule where the change back to standard
1108# time took place on Sunday night instead of Saturday night to avoid
1109# conflicts with the Jewish New Year. In 1999, the change to
1110# daylight savings time was still on a Friday morning but from
1111# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
1112# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
1113# 1999 only. In the year 2000, the change to daylight savings time was
1114# similar to 1999, but although the change back will be on a Friday, it
1115# will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
1116# changes to/from will take place at 1 a.m. old time, but now there is no
1117# rule as to what day of the week it will take place in as the start date
1118# (except in 2003) is the night after the Passover Seder (i.e. the eve
1119# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
1120# (except in 2002) is three nights before Yom Kippur [Day of Atonement]
1121# (the eve of the 7th of Tishrei in the lunar Hebrew calendar).

1265# Occupation authorities imposed daylight-saving time on Japan on
1266# [1948-05-01].... But lack of prior debate and the execution of
1267# daylight-saving time just three days after the bill was passed generated
1268# deep hatred of the concept.... The Diet unceremoniously passed a bill to
1269# dump the unpopular system in October 1951, less than a month after the San
1270# Francisco Peace Treaty was signed. (A government poll in 1951 showed 53%
1271# of the Japanese wanted to scrap daylight-saving time, as opposed to 30% who
1272# wanted to keep it.)

1295# The ordinance No. 51 (1886) established "standard time" in Japan,
1296# which stands for the time on E 135 degree.
1297# In the ordinance No. 167 (1895), "standard time" was renamed to "central
1298# standard time". And the same ordinance also established "western standard
1299# time", which stands for the time on E 120 degree.... But "western standard
1300# time" was abolished in the ordinance No. 529 (1937). In the ordinance No.
1301# 167, there is no mention regarding for what place western standard time is
1302# standard....
1303#
1304# I wrote "ordinance" above, but I don't know how to translate.
1305# In Japanese it's "chokurei", which means ordinance from emperor.

1688# "Time: Mongolia has two time zones. Three westernmost provinces of

1693# From Rives McDow (1999-12-13):
1694# Mongolia discontinued the use of daylight savings time in 1999; 1998

1696# unsure of, but most probably it was similar to Russia, except for the time

1698# Some maps in the past have indicated that there was an additional time

1701
1702# From Paul Eggert (1999-12-15):
1703# Naming and spelling is tricky in Mongolia.

1705# the capital of the Hovd province is sometimes called Hovd, sometimes Dund-Us,

2033
2034# From Amos Shapir (1998-02-15):
2035#
2036# From 1917 until 1948-05-15, all of Palestine, including the parts now
2037# known as the Gaza Strip and the West Bank, was under British rule.
2038# Therefore the rules given for Israel for that period, apply there too...
2039#
2040# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
2041# (except a short occupation by Israel from 1956-11 till 1957-03, but no
2042# time zone was affected then). It was never formally annexed to Egypt,
2043# though.
2044#
2045# The rest of Palestine was under Jordanian rule at that time, formally
2046# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
2047# the country's previous name of "the Hashemite Kingdom of the
2048# Trans-Jordan"). So the rules for Jordan for that time apply. Major
2049# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
2050# East Jerusalem.
2051#
2052# Both areas were occupied by Israel in June 1967, but not annexed (except
2053# for East Jerusalem). They were on Israel time since then; there might
2054# have been a Military Governor's order about time zones, but I'm not aware
2055# of any (such orders may have been issued semi-annually whenever summer
2056# time was in effect, but maybe the legal aspect of time was just neglected).
2057#
2058# The Palestinian Authority was established in 1993, and got hold of most
2059# towns in the West Bank and Gaza by 1995. I know that in order to
2060# demonstrate...independence, they have been switching to
2061# summer time and back on a different schedule than Israel's, but I don't
2062# know when this was started, or what algorithm is used (most likely the
2063# Jordanian one).
2064#
2065# To summarize, the table should probably look something like that:
2066#
2067# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
2068# ------------+-----------+-----------+-----------+-----------
2069# Israel | Zion | Zion | Zion | Zion
2070# West bank | Zion | Jordan | Zion | Jordan
2071# Gaza | Zion | Egypt | Zion | Jordan
2072#
2073# I guess more info may be available from the PA's web page (if/when they
2074# have one).
2075
2076# From Paul Eggert (2006-03-22):
2077# Shanks & Pottenger write that Gaza did not observe DST until 1957, but go
2078# with Shapir and assume that it observed DST from 1940 through 1947,
2079# and that it used Jordanian rules starting in 1996.
2080# We don't yet need a separate entry for the West Bank, since
2081# the only differences between it and Gaza that we know about
2082# occurred before our cutoff date of 1970.
2083# However, as we get more information, we may need to add entries
2084# for parts of the West Bank as they transitioned from Israel's rules
2085# to Palestine's rules.
2086
2087# From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time,
2088# forwarded by Ephraim Silverberg:
2089#
2090# Despite the fact that Israel changed over to daylight savings time
2091# last week, the PLO Authority (PA) has decided not to turn its clocks
2092# one-hour forward at this time. As a sign of independence from Israeli rule,
2093# the PA has decided to implement DST in April.

2107
2108# From Steffen Thorsen (2005-11-23):
2109# A user from Gaza reported that Gaza made the change early because of

2111# there is a good chance next year's end date will be around two weeks

2113
2114# From Steffen Thorsen (2006-08-17):
2115# I was informed by a user in Bethlehem that in Bethlehem it started the
2116# same day as Israel, and after checking with other users in the area, I
2117# was informed that they started DST one day after Israel. I was not

2119# Gaza changed as well, but presumed Gaza to follow the same rules as

2128# I guess it is likely that next year's date will be moved as well,

2131# From Jesper Norgaard Welen (2007-09-18):
2132# According to Steffen Thorsen's web site the Gaza Strip and the rest of the
2133# Palestinian territories left DST early on 13.th. of September at 2:00.
2134
2135# From Paul Eggert (2007-09-20):
2136# My understanding is that Gaza and the West Bank disagree even over when

2138# surprised if they agreed about DST. But for now, assume they agree.

2476# [The Tamil Tigers] never accepted the original 1996 time change and simply

2478# Time (GMT), in line with neighbor India.
2479# From Paul Eggert (2006-04-18):

2482
2483# From K Sethu (2006-04-25):
2484# I think the abbreviation LKT originated from the world of computers at
2485# the time of or subsequent to the time zone changes by SL Government
2486# twice in 1996 and probably SL Government or its standardization
2487# agencies never declared an abbreviation as a national standard.
2488#
2489# I recollect before the recent change the government annoucemments
2490# mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka
2491# Time and no mention was made about the abbreviation.
2492#
2493# If we look at Sri Lanka Department of Government's "Official News
2494# Website of Sri Lanka" ... http://www.news.lk/ we can see that they
2495# use SLT as abbreviation in time stamp at the beginning of each news
2496# item....
2497#
2498# Within Sri Lanka I think LKT is well known among computer users and
2499# adminsitrators. In my opinion SLT may not be a good choice because the
2500# nation's largest telcom / internet operator Sri Lanka Telcom is well
2501# known by that abbreviation - simply as SLT (there IP domains are
2502# slt.lk and sltnet.lk).
2503#
2504# But if indeed our government has adopted SLT as standard abbreviation
2505# (that we have not known so far) then it is better that it be used for
2506# all computers.
2507
2508# From Paul Eggert (2006-04-25):

2753# From Paul Eggert (2013-02-21):
2754# Milne gives 7:16:56 for the meridian of Saigon in 1899, as being
2755# used in Lower Laos, Cambodia, and Annam. But this is quite a ways
2756# from Saigon's location. For now, ignore this and stick with Shanks
2757# and Pottenger.
2758
2759# From Arthur David Olson (2008-03-18):
2760# The English-language name of Vietnam's most populous city is "Ho Chi Min City";
2761# we use Ho_Chi_Minh below to avoid a name of more than 14 characters.
