9# From Paul Eggert (2006-03-22):
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# A reliable and entertaining source about time zones is
29# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
30#
31# I invented the abbreviations marked `*' in the following table;
32# the rest are from earlier versions of this file, or from other sources.

86# Armenia
87# From Paul Eggert (2006-03-22):
88# Shanks & Pottenger have Yerevan switching to 3:00 (with Russian DST)
89# in spring 1991, then to 4:00 with no DST in fall 1995, then
90# readopting Russian DST in 1997.  Go with Shanks & Pottenger, even
91# when they disagree with others.  Edgar Der-Danieliantz
92# reported (1996-05-04) that Yerevan probably wouldn't use DST
93# in 1996, though it did use DST in 1995.  IATA SSIM (1991/1998) reports that
94# Armenia switched from 3:00 to 4:00 in 1998 and observed DST after 1991,
95# but started switching at 3:00s in 1998.

283# China
284
285# From Guy Harris:
286# People's Republic of China.  Yes, they really have only one time zone.
287
288# From Bob Devine (1988-01-28):
289# No they don't.  See TIME mag, 1986-02-17 p.52.  Even though
290# China is across 4 physical time zones, before Feb 1, 1986 only the
291# Peking (Bejing) time zone was recognized.  Since that date, China
292# has two of 'em -- Peking's and Urumqi (named after the capital of
293# the Xinjiang Uyghur Autonomous Region).  I don't know about DST for it.
294#
295# . . .I just deleted the DST table and this editor makes it too
296# painful to suck in another copy..  So, here is what I have for
297# DST start/end dates for Peking's time zone (info from AP):
298#
299#     1986 May 4 - Sept 14
300#     1987 mid-April - ??
301
302# From U. S. Naval Observatory (1989-01-19):
303# CHINA               8 H  AHEAD OF UTC  ALL OF CHINA, INCL TAIWAN
304# CHINA               9 H  AHEAD OF UTC  APR 17 - SEP 10
305
306# From Paul Eggert (2006-03-22):
307# Shanks & Pottenger write that China (except for Hong Kong and Macau)
308# has had a single time zone since 1980 May 1, observing summer DST
309# from 1986 through 1991; this contradicts Devine's
310# note about Time magazine, though apparently _something_ happened in 1986.
311# Go with Shanks & Pottenger for now.  I made up names for the other

323# From Anthony Fok (2001-12-20):
324# BTW, I did some research on-line and found some info regarding these five
325# historic timezones from some Taiwan websites.  And yes, there are official
326# Chinese names for these locales (before 1949).
327#
328# From Jesper Norgaard Welen (2006-07-14):
329# I have investigated the timezones around 1970 on the
330# http://www.astro.com/atlas site [with provinces and county
331# boundaries summarized below]....  A few other exceptions were two
332# counties on the Sichuan side of the Xizang-Sichuan border,
333# counties Dege and Baiyu which lies on the Sichuan side and are
334# therefore supposed to be GMT+7, Xizang region being GMT+6, but Dege
335# county is GMT+8 according to astro.com while Baiyu county is GMT+6
336# (could be true), for the moment I am assuming that those two
337# counties are mistakes in the astro.com data.
338
339# From Paul Eggert (2008-02-11):
340# I just now checked Google News for western news sources that talk
341# about China's single time zone, and couldn't find anything before 1986
342# talking about China being in one time zone.  (That article was: Jim
343# Mann, "A clumsy embrace for another western custom: China on daylight
344# time--sort of", Los Angeles Times, 1986-05-05.  By the way, this
345# article confirms the tz database's data claiming that China began
346# observing daylight saving time in 1986.
347#
348# From Thomas S. Mullaney (2008-02-11):
349# I think you're combining two subjects that need to treated 
350# separately: daylight savings (which, you're correct, wasn't 
351# implemented until the 1980s) and the unified time zone centered near 
352# Beijing (which was implemented in 1949). Briefly, there was also a 
353# "Lhasa Time" in Tibet and "Urumqi Time" in Xinjiang. The first was 
354# ceased, and the second eventually recognized (again, in the 1980s).
355#
356# From Paul Eggert (2008-06-30):
357# There seems to be a good chance China switched to a single time zone in 1949
358# rather than in 1980 as Shanks & Pottenger have it, but we don't have a
359# reliable documentary source saying so yet, so for now we still go with
360# Shanks & Pottenger.

402# From Luther Ma (2009-10-17):
403# Almost all (>99.9%) ethnic Chinese (properly ethnic Han) living in
404# Xinjiang use Chinese Standard Time. Some are aware of Xinjiang time,
405# but have no need of it. All planes, trains, and schools function on
406# what is called "Beijing time." When Han make an appointment in Chinese
407# they implicitly use Beijing time.
408#
409# On the other hand, ethnic Uyghurs, who make up about half the
410# population of Xinjiang, typically use "Xinjiang time" which is two
411# hours behind Beijing time, or UTC +0600. The government of the Xinjiang
412# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as
413# local governments such as the Urumqi city government use both times in
414# publications, referring to what is popularly called Xinjiang time as
415# "Urumqi time." When Uyghurs make an appointment in the Uyghur language
416# they almost invariably use Xinjiang time.
417#
418# (Their ethnic Han compatriots would typically have no clue of its
419# widespread use, however, because so extremely few of them are fluent in
420# Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.)
421#
422# (...As with the rest of China there was a brief interval ending in 1990
423# or 1991 when summer time was in use.  The confusion was severe, with
424# the province not having dual times but four times in use at the same
425# time. Some areas remained on standard Xinjiang time or Beijing time and
426# others moving their clocks ahead.)

443# From Luther Ma (2009-11-19):
444# With the risk of being redundant to previous answers these are the most common
445# English "transliterations" (w/o using non-English symbols):
446#
447# 1. Wulumuqi...
448# 2. Kashi...
449# 3. Urumqi...
450# 4. Kashgar...
451# ...
452# 5. It seems that Uyghurs in Urumqi has been using Xinjiang since at least the
453# 1960's. I know of one Han, now over 50, who grew up in the surrounding
454# countryside and used Xinjiang time as a child.
455#
456# 6. Likewise for Kashgar and the rest of south Xinjiang I don't know of any
457# start date for Xinjiang time.
458#
459# Without having access to local historical records, nor the ability to legally
460# publish them, I would go with October 1, 1949, when Xinjiang became the Uyghur
461# Autonomous Region under the PRC. (Before that Uyghurs, of course, would also
462# not be using Beijing time, but some local time.)

473# it is not [an] observatory, but the official meteorological agency of HK,

637# We have no details, but we'll guess they didn't move the clocks back in fall.

643#
644# From the BBC via Joseph S. Myers (2004-06-27):
645#
646# Georgia moved closer to Western Europe on Sunday...  The former Soviet
647# republic has changed its time zone back to that of Moscow.  As a result it
648# is now just four hours ahead of Greenwich Mean Time, rather than five hours

653# From Teimuraz Abashidze (2005-11-07):
654# Government of Georgia ... decided to NOT CHANGE daylight savings time on

656# Currently, we are in fact GMT +4:00, as before 30 October it was GMT

658# about it.  As far as I can find, I was told, that there is no document,

776# Iran
777
778# From Roozbeh Pournader (2003-03-15):
779# This is an English translation of what I just found (originally in Persian).
780# The Gregorian dates in brackets are mine:
781#
782#	Official Newspaper No. 13548-1370/6/25 [1991-09-16]
783#	No. 16760/T233 H				1370/6/10 [1991-09-01]
784#
785#	The Rule About Change of the Official Time of the Country
786#
787#	The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14],
788#	based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13]
789#	of the Country's Organization for Official and Employment Affairs,
790#	and referring to the law for equating the working hours of workers
791#	and officers in the whole country dated 1359/4/23 [1980-07-14], and
792#	for synchronizing the official times of the country, agreed that:
793#
794#	The official time of the country will should move forward one hour
795#	at the 24[:00] hours of the first day of Farvardin and should return
796#	to its previous state at the 24[:00] hours of the 30th day of
797#	Shahrivar.
798#
799#	First Deputy to the President - Hassan Habibi
800#
801# From personal experience, that agrees with what has been followed
802# for at least the last 5 years.  Before that, for a few years, the
803# date used was the first Thursday night of Farvardin and the last
804# Thursday night of Shahrivar, but I can't give exact dates....
805# I have also changed the abbreviations to what is considered correct
806# here in Iran, IRST for regular time and IRDT for daylight saving time.
807#
808# From Roozbeh Pournader (2005-04-05):
809# The text of the Iranian law, in effect since 1925, clearly mentions
810# that the true solar year is the measure, and there is no arithmetic
811# leap year calculation involved.  There has never been any serious
812# plan to change that law....
813#
814# From Paul Eggert (2006-03-22):
815# Go with Shanks & Pottenger before Sept. 1991, and with Pournader thereafter.
816# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,
817# stopping after 2037 when 32-bit time_t's overflow.
818# That cal-persia used Birashk's approximation, which disagrees with the solar
819# calendar predictions for the year 2025, so I corrected those dates by hand.
820#
821# From Oscar van Vlijmen (2005-03-30), writing about future
822# discrepancies between cal-persia and the Iranian calendar:
823# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
824# the vernal equinox and that gets so close to 12:00 some local
825# Iranian time that the definition of the correct location needs to be
826# known exactly, amongst other factors.  2157 is even closer:
827# 2157-03-20 08:37:15.5 UT.  But the Gregorian year 2025 should give
828# no interpretation problem whatsoever.  By the way, another instant
829# in the near future where there will be a discrepancy between
830# arithmetical and astronomical Iranian calendars will be in 2058:
831# vernal equinox on 2058-03-20 09:03:05.9 UT.  The Java version of
832# Reingold's/Dershowitz' calculator gives correctly the Gregorian date
833# 2058-03-21 for 1 Farvardin 1437 (astronomical).
834#
835# From Steffen Thorsen (2006-03-22):
836# Several of my users have reported that Iran will not observe DST anymore:
837# http://www.irna.ir/en/news/view/line-17/0603193812164948.htm
838#
839# From Reuters (2007-09-16), with a heads-up from Jesper Norgaard Welen:
840# ... the Guardian Council ... approved a law on Sunday to re-introduce
841# daylight saving time ...
842# http://uk.reuters.com/article/oilRpt/idUKBLA65048420070916
843#
844# From Roozbeh Pournader (2007-11-05):
845# This is quoted from Official Gazette of the Islamic Republic of
846# Iran, Volume 63, Number 18242, dated Tuesday 1386/6/24
847# [2007-10-16]. I am doing the best translation I can:...
848# The official time of the country will be moved forward for one hour
849# on the 24 hours of the first day of the month of Farvardin and will
850# be changed back to its previous state on the 24 hours of the

911# Iraq
912#
913# From Jonathan Lennox (2000-06-12):
914# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
915# the U.S. edition) on the Iraqi Kurds contains a paragraph:
916# "The three northern provinces ... switched their clocks this spring and
917# are an hour ahead of Baghdad."
918#
919# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
920# In the past, some Kurdish nationalists, as a protest to the Iraqi
921# Government, did not adhere to daylight saving time.  They referred
922# to daylight saving as Saddam time.  But, as of today, the time zone
923# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
924#
925# So we'll ignore the Economist's claim.

963# Israel
964
965# From Ephraim Silverberg (2001-01-11):
966#
967# I coined "IST/IDT" circa 1988.  Until then there were three
968# different abbreviations in use:
969#
970# JST  Jerusalem Standard Time [Danny Braniss, Hebrew University]
971# IZT  Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
972# EEST Eastern Europe Standard Time [used by almost everyone else]
973#
974# Since timezones should be called by country and not capital cities,
975# I ruled out JST.  As Israel is in Asia Minor and not Eastern Europe,
976# EEST was equally unacceptable.  Since "zonal" was not compatible with
977# any other timezone abbreviation, I felt that 'IST' was the way to go
978# and, indeed, it has received almost universal acceptance in timezone
979# settings in Israeli computers.
980#
981# In any case, I am happy to share timezone abbreviations with India,
982# high on my favorite-country list (and not only because my wife's
983# family is from India).

1028# From Ephraim Silverberg
1029# (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17, 2000-07-25, 2004-12-22,
1030# and 2005-02-17):
1031
1032# According to the Office of the Secretary General of the Ministry of
1033# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
1034# One thing is entrenched in law, however: that there must be at least 150
1035# days of daylight savings time annually.  From 1993-1998, the change to
1036# daylight savings time was on a Friday morning from midnight IST to
1037# 1 a.m IDT; up until 1998, the change back to standard time was on a
1038# Saturday night from midnight daylight savings time to 11 p.m. standard
1039# time.  1996 is an exception to this rule where the change back to standard
1040# time took place on Sunday night instead of Saturday night to avoid
1041# conflicts with the Jewish New Year.  In 1999, the change to
1042# daylight savings time was still on a Friday morning but from
1043# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
1044# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
1045# 1999 only.  In the year 2000, the change to daylight savings time was

1205
1206# `9:00' and `JST' is from Guy Harris.
1207
1208# From Paul Eggert (1995-03-06):
1209# Today's _Asahi Evening News_ (page 4) reports that Japan had
1210# daylight saving between 1948 and 1951, but ``the system was discontinued
1211# because the public believed it would lead to longer working hours.''
1212
1213# From Mayumi Negishi in the 2005-08-10 Japan Times
1214# <http://www.japantimes.co.jp/cgi-bin/getarticle.pl5?nn20050810f2.htm>:
1215# Occupation authorities imposed daylight-saving time on Japan on
1216# [1948-05-01]....  But lack of prior debate and the execution of
1217# daylight-saving time just three days after the bill was passed generated
1218# deep hatred of the concept....  The Diet unceremoniously passed a bill to
1219# dump the unpopular system in October 1951, less than a month after the San
1220# Francisco Peace Treaty was signed.  (A government poll in 1951 showed 53%
1221# of the Japanese wanted to scrap daylight-saving time, as opposed to 30% who
1222# wanted to keep it.)
1223
1224# From Paul Eggert (2006-03-22):
1225# Shanks & Pottenger write that DST in Japan during those years was as follows:

1231# but the only locations using it (for birth certificates, presumably, since
1232# their audience is astrologers) were US military bases.  For now, assume
1233# that for most purposes daylight-saving time was observed; otherwise, what
1234# would have been the point of the 1951 poll?
1235
1236# From Hideyuki Suzuki (1998-11-09):
1237# 'Tokyo' usually stands for the former location of Tokyo Astronomical
1238# Observatory: E 139 44' 40".90 (9h 18m 58s.727), N 35 39' 16".0.
1239# This data is from 'Rika Nenpyou (Chronological Scientific Tables) 1996'
1240# edited by National Astronomical Observatory of Japan....
1241# JST (Japan Standard Time) has been used since 1888-01-01 00:00 (JST).
1242# The law is enacted on 1886-07-07.
1243
1244# From Hideyuki Suzuki (1998-11-16):
1245# The ordinance No. 51 (1886) established "standard time" in Japan,
1246# which stands for the time on E 135 degree.
1247# In the ordinance No. 167 (1895), "standard time" was renamed to "central
1248# standard time".  And the same ordinance also established "western standard
1249# time", which stands for the time on E 120 degree....  But "western standard
1250# time" was abolished in the ordinance No. 529 (1937).  In the ordinance No.
1251# 167, there is no mention regarding for what place western standard time is
1252# standard....
1253#
1254# I wrote "ordinance" above, but I don't know how to translate.
1255# In Japanese it's "chokurei", which means ordinance from emperor.
1256
1257# Shanks & Pottenger claim JST in use since 1896, and that a few
1258# places (e.g. Ishigaki) use +0800; go with Suzuki.  Guess that all
1259# ordinances took effect on Jan 1.

1364# From Paul Eggert (1996-11-22):
1365# Andrew Evtichov (1996-04-13) writes that Kazakhstan
1366# stayed in sync with Moscow after 1990, and that Aqtobe (formerly Aktyubinsk)
1367# and Aqtau (formerly Shevchenko) are the largest cities in their zones.
1368# Guess that Aqtau and Aqtobe diverged in 1995, since that's the first time
1369# IATA SSIM mentions a third time zone in Kazakhstan.
1370
1371# From Paul Eggert (2006-03-22):
1372# German Iofis, ELSI, Almaty (2001-10-09) reports that Kazakhstan uses
1373# RussiaAsia rules, instead of switching at 00:00 as the IATA has it.
1374# Go with Shanks & Pottenger, who have them always using RussiaAsia rules.
1375# Also go with the following claims of Shanks & Pottenger:
1376#
1377# - Kazakhstan did not observe DST in 1991.
1378# - Qyzylorda switched from +5:00 to +6:00 on 1992-01-19 02:00.
1379# - Oral switched from +5:00 to +4:00 in spring 1989.

1381# <a href="http://www.kazsociety.org.uk/news/2005/03/30.htm">
1382# From Kazakhstan Embassy's News Bulletin #11 (2005-03-21):
1383# </a>
1384# The Government of Kazakhstan passed a resolution March 15 abolishing
1385# daylight saving time citing lack of economic benefits and health
1386# complications coupled with a decrease in productivity.
1387#
1388# From Branislav Kojic (in Astana) via Gwillim Law (2005-06-28):
1389# ... what happened was that the former Kazakhstan Eastern time zone
1390# was "blended" with the Central zone.  Therefore, Kazakhstan now has
1391# two time zones, and difference between them is one hour.  The zone
1392# closer to UTC is the former Western zone (probably still called the
1393# same), encompassing four provinces in the west: Aqtobe, Atyrau,
1394# Mangghystau, and West Kazakhstan.  The other zone encompasses
1395# everything else....  I guess that would make Kazakhstan time zones
1396# de jure UTC+5 and UTC+6 respectively.

1778# 15th October each year".  This agrees with McDow's 04-07 at 00:00,
1779# but disagrees about the October transition, and makes it sound like
1780# it's not on a trial basis.  Also, the "between the first Saturday

1932# Palestine
1933
1934# From Amos Shapir (1998-02-15):
1935#
1936# From 1917 until 1948-05-15, all of Palestine, including the parts now
1937# known as the Gaza Strip and the West Bank, was under British rule.
1938# Therefore the rules given for Israel for that period, apply there too...
1939#
1940# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
1941# (except a short occupation by Israel from 1956-11 till 1957-03, but no
1942# time zone was affected then).  It was never formally annexed to Egypt,
1943# though.
1944#
1945# The rest of Palestine was under Jordanian rule at that time, formally
1946# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
1947# the country's previous name of "the Hashemite Kingdom of the
1948# Trans-Jordan").  So the rules for Jordan for that time apply.  Major
1949# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
1950# East Jerusalem.
1951#
1952# Both areas were occupied by Israel in June 1967, but not annexed (except
1953# for East Jerusalem).  They were on Israel time since then; there might
1954# have been a Military Governor's order about time zones, but I'm not aware
1955# of any (such orders may have been issued semi-annually whenever summer
1956# time was in effect, but maybe the legal aspect of time was just neglected).
1957#
1958# The Palestinian Authority was established in 1993, and got hold of most
1959# towns in the West Bank and Gaza by 1995.  I know that in order to
1960# demonstrate...independence, they have been switching to
1961# summer time and back on a different schedule than Israel's, but I don't
1962# know when this was started, or what algorithm is used (most likely the
1963# Jordanian one).
1964#
1965# To summarize, the table should probably look something like that:
1966#
1967# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
1968# ------------+-----------+-----------+-----------+-----------
1969# Israel      | Zion      | Zion      | Zion      | Zion
1970# West bank   | Zion      | Jordan    | Zion      | Jordan
1971# Gaza        | Zion      | Egypt     | Zion      | Jordan
1972#
1973# I guess more info may be available from the PA's web page (if/when they
1974# have one).
1975
1976# From Paul Eggert (2006-03-22):
1977# Shanks & Pottenger write that Gaza did not observe DST until 1957, but go
1978# with Shapir and assume that it observed DST from 1940 through 1947,
1979# and that it used Jordanian rules starting in 1996.
1980# We don't yet need a separate entry for the West Bank, since
1981# the only differences between it and Gaza that we know about
1982# occurred before our cutoff date of 1970.
1983# However, as we get more information, we may need to add entries
1984# for parts of the West Bank as they transitioned from Israel's rules
1985# to Palestine's rules.  If you have more info about this, please

2229# [The Tamil Tigers] never accepted the original 1996 time change and simply
2230# kept their clocks set five and a half hours ahead of Greenwich Mean
2231# Time (GMT), in line with neighbor India.
2232# From Paul Eggert (2006-04-18):
2233# People who live in regions under Tamil control can use [TZ='Asia/Kolkata'],
2234# as that zone has agreed with the Tamil areas since our cutoff date of 1970.
2235
2236# From K Sethu (2006-04-25):
2237# I think the abbreviation LKT originated from the world of computers at
2238# the time of or subsequent to the time zone changes by SL Government
2239# twice in 1996 and probably SL Government or its standardization
2240# agencies never declared an abbreviation as a national standard.
2241#
2242# I recollect before the recent change the government annoucemments
2243# mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka
2244# Time and no mention was made about the abbreviation.
2245#
2246# If we look at Sri Lanka Department of Government's "Official News
2247# Website of Sri Lanka" ... http://www.news.lk/ we can see that they
2248# use SLT as abbreviation in time stamp at the beginning of each news
2249# item....
2250#
2251# Within Sri Lanka I think LKT is well known among computer users and
2252# adminsitrators.  In my opinion SLT may not be a good choice because the
2253# nation's largest telcom / internet operator Sri Lanka Telcom is well
2254# known by that abbreviation - simply as SLT (there IP domains are
2255# slt.lk and sltnet.lk).
2256#
2257# But if indeed our government has adopted SLT as standard abbreviation
2258# (that we have not known so far) then  it is better that it be used for
2259# all computers.
2260
2261# From Paul Eggert (2006-04-25):
2262# One possibility is that we wait for a bit for the dust to settle down
2263# and then see what people actually say in practice.
