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.

281# China
282
283# From Guy Harris:
284# People's Republic of China.  Yes, they really have only one time zone.
285
286# From Bob Devine (1988-01-28):
287# No they don't.  See TIME mag, 1986-02-17 p.52.  Even though
288# China is across 4 physical time zones, before Feb 1, 1986 only the
289# Peking (Bejing) time zone was recognized.  Since that date, China
290# has two of 'em -- Peking's and Urumqi (named after the capital of
291# the Xinjiang Uyghur Autonomous Region).  I don't know about DST for it.
292#
293# . . .I just deleted the DST table and this editor makes it too
294# painful to suck in another copy..  So, here is what I have for
295# DST start/end dates for Peking's time zone (info from AP):
296#
297#     1986 May 4 - Sept 14
298#     1987 mid-April - ??
299
300# From U. S. Naval Observatory (1989-01-19):

302# CHINA               9 H  AHEAD OF UTC  APR 17 - SEP 10
303
304# From Paul Eggert (2006-03-22):
305# Shanks & Pottenger write that China (except for Hong Kong and Macau)
306# has had a single time zone since 1980 May 1, observing summer DST
307# from 1986 through 1991; this contradicts Devine's
308# note about Time magazine, though apparently _something_ happened in 1986.
309# Go with Shanks & Pottenger for now.  I made up names for the other

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

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

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

665# From the BBC via Joseph S. Myers (2004-06-27):
666#
667# Georgia moved closer to Western Europe on Sunday...  The former Soviet

669# is now just four hours ahead of Greenwich Mean Time, rather than five hours
670# ahead.  The switch was decreed by the pro-Western president of Georgia,

677# Currently, we are in fact GMT +4:00, as before 30 October it was GMT
678# +3:00.... The problem is, there is NO FORMAL LAW or governmental document
679# about it.  As far as I can find, I was told, that there is no document,
680# because we just DIDN'T ISSUE document about switching to winter time....

748# <http://www.sumatera-inc.com/go_to_invest/about_indonesia.asp#standtime>
749# says that Indonesia's time zones changed on 1988-01-01.  Looking at some
750# time zone maps, I think that must refer to Western Borneo (Kalimantan Barat
751# and Kalimantan Tengah) switching from UTC+8 to UTC+7.
752#
753# From Paul Eggert (2007-03-10):
754# Here is another correction to Shanks & Pottenger.
755# JohnTWB writes that Japanese forces did not surrender control in
756# Indonesia until 1945-09-01 00:00 at the earliest (in Jakarta) and
757# other formal surrender ceremonies were September 9, 11, and 13, plus
758# September 12 for the regional surrender to Mountbatten in Singapore.
759# These would be the earliest possible times for a change.
760# Regimes horaires pour le monde entier, by Henri Le Corre, (Editions
761# Traditionnelles, 1987, Paris) says that Java and Madura switched
762# from JST to UTC+07:30 on 1945-09-23, and gives 1944-09-01 for Jayapura
763# (Hollandia).  For now, assume all Indonesian locations other than Jayapura
764# switched on 1945-09-23.

799# From Roozbeh Pournader (2003-03-15):
800# This is an English translation of what I just found (originally in Persian).
801# The Gregorian dates in brackets are mine:
802#
803#	Official Newspaper No. 13548-1370/6/25 [1991-09-16]
804#	No. 16760/T233 H				1370/6/10 [1991-09-01]
805#
806#	The Rule About Change of the Official Time of the Country
807#
808#	The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14],
809#	based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13]
810#	of the Country's Organization for Official and Employment Affairs,
811#	and referring to the law for equating the working hours of workers
812#	and officers in the whole country dated 1359/4/23 [1980-07-14], and
813#	for synchronizing the official times of the country, agreed that:
814#
815#	The official time of the country will should move forward one hour
816#	at the 24[:00] hours of the first day of Farvardin and should return
817#	to its previous state at the 24[:00] hours of the 30th day of
818#	Shahrivar.
819#
820#	First Deputy to the President - Hassan Habibi
821#
822# From personal experience, that agrees with what has been followed
823# for at least the last 5 years.  Before that, for a few years, the
824# date used was the first Thursday night of Farvardin and the last
825# Thursday night of Shahrivar, but I can't give exact dates....
826# I have also changed the abbreviations to what is considered correct
827# here in Iran, IRST for regular time and IRDT for daylight saving time.
828#
829# From Roozbeh Pournader (2005-04-05):
830# The text of the Iranian law, in effect since 1925, clearly mentions
831# that the true solar year is the measure, and there is no arithmetic
832# leap year calculation involved.  There has never been any serious
833# plan to change that law....
834#
835# From Paul Eggert (2006-03-22):
836# Go with Shanks & Pottenger before Sept. 1991, and with Pournader thereafter.
837# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,
838# stopping after 2037 when 32-bit time_t's overflow.
839# That cal-persia used Birashk's approximation, which disagrees with the solar
840# calendar predictions for the year 2025, so I corrected those dates by hand.
841#
842# From Oscar van Vlijmen (2005-03-30), writing about future
843# discrepancies between cal-persia and the Iranian calendar:
844# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
845# the vernal equinox and that gets so close to 12:00 some local
846# Iranian time that the definition of the correct location needs to be
847# known exactly, amongst other factors.  2157 is even closer:
848# 2157-03-20 08:37:15.5 UT.  But the Gregorian year 2025 should give
849# no interpretation problem whatsoever.  By the way, another instant
850# in the near future where there will be a discrepancy between
851# arithmetical and astronomical Iranian calendars will be in 2058:
852# vernal equinox on 2058-03-20 09:03:05.9 UT.  The Java version of
853# Reingold's/Dershowitz' calculator gives correctly the Gregorian date
854# 2058-03-21 for 1 Farvardin 1437 (astronomical).
855#
856# From Steffen Thorsen (2006-03-22):
857# Several of my users have reported that Iran will not observe DST anymore:
858# http://www.irna.ir/en/news/view/line-17/0603193812164948.htm
859#
860# From Reuters (2007-09-16), with a heads-up from Jesper Norgaard Welen:
861# ... the Guardian Council ... approved a law on Sunday to re-introduce
862# daylight saving time ...
863# http://uk.reuters.com/article/oilRpt/idUKBLA65048420070916
864#
865# From Roozbeh Pournader (2007-11-05):
866# This is quoted from Official Gazette of the Islamic Republic of
867# Iran, Volume 63, Number 18242, dated Tuesday 1386/6/24
868# [2007-10-16]. I am doing the best translation I can:...
869# The official time of the country will be moved forward for one hour
870# on the 24 hours of the first day of the month of Farvardin and will
871# be changed back to its previous state on the 24 hours of the
872# thirtieth day of Shahrivar.

933#
934# From Jonathan Lennox (2000-06-12):
935# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
936# the U.S. edition) on the Iraqi Kurds contains a paragraph:
937# "The three northern provinces ... switched their clocks this spring and
938# are an hour ahead of Baghdad."
939#
940# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
941# In the past, some Kurdish nationalists, as a protest to the Iraqi
942# Government, did not adhere to daylight saving time.  They referred
943# to daylight saving as Saddam time.  But, as of today, the time zone
944# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
945#
946# So we'll ignore the Economist's claim.

984# Israel
985
986# From Ephraim Silverberg (2001-01-11):
987#
988# I coined "IST/IDT" circa 1988.  Until then there were three
989# different abbreviations in use:
990#
991# JST  Jerusalem Standard Time [Danny Braniss, Hebrew University]
992# IZT  Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
993# EEST Eastern Europe Standard Time [used by almost everyone else]
994#
995# Since timezones should be called by country and not capital cities,
996# I ruled out JST.  As Israel is in Asia Minor and not Eastern Europe,
997# EEST was equally unacceptable.  Since "zonal" was not compatible with
998# any other timezone abbreviation, I felt that 'IST' was the way to go
999# and, indeed, it has received almost universal acceptance in timezone
1000# settings in Israeli computers.
1001#
1002# In any case, I am happy to share timezone abbreviations with India,
1003# high on my favorite-country list (and not only because my wife's
1004# family is from India).

1049# From Ephraim Silverberg
1050# (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17, 2000-07-25, 2004-12-22,
1051# and 2005-02-17):
1052
1053# According to the Office of the Secretary General of the Ministry of
1054# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
1055# One thing is entrenched in law, however: that there must be at least 150
1056# days of daylight savings time annually.  From 1993-1998, the change to
1057# daylight savings time was on a Friday morning from midnight IST to
1058# 1 a.m IDT; up until 1998, the change back to standard time was on a
1059# Saturday night from midnight daylight savings time to 11 p.m. standard
1060# time.  1996 is an exception to this rule where the change back to standard
1061# time took place on Sunday night instead of Saturday night to avoid
1062# conflicts with the Jewish New Year.  In 1999, the change to
1063# daylight savings time was still on a Friday morning but from
1064# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
1065# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
1066# 1999 only.  In the year 2000, the change to daylight savings time was
1067# similar to 1999, but although the change back will be on a Friday, it
1068# will take place from 1 a.m. IDT to midnight IST.  Starting in 2001, all
1069# changes to/from will take place at 1 a.m. old time, but now there is no
1070# rule as to what day of the week it will take place in as the start date
1071# (except in 2003) is the night after the Passover Seder (i.e. the eve
1072# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
1073# (except in 2002) is three nights before Yom Kippur [Day of Atonement]
1074# (the eve of the 7th of Tishrei in the lunar Hebrew calendar).

1227# `9:00' and `JST' is from Guy Harris.
1228
1229# From Paul Eggert (1995-03-06):
1230# Today's _Asahi Evening News_ (page 4) reports that Japan had
1231# daylight saving between 1948 and 1951, but ``the system was discontinued
1232# because the public believed it would lead to longer working hours.''
1233
1234# From Mayumi Negishi in the 2005-08-10 Japan Times
1235# <http://www.japantimes.co.jp/cgi-bin/getarticle.pl5?nn20050810f2.htm>:
1236# Occupation authorities imposed daylight-saving time on Japan on
1237# [1948-05-01]....  But lack of prior debate and the execution of
1238# daylight-saving time just three days after the bill was passed generated
1239# deep hatred of the concept....  The Diet unceremoniously passed a bill to
1240# dump the unpopular system in October 1951, less than a month after the San
1241# Francisco Peace Treaty was signed.  (A government poll in 1951 showed 53%
1242# of the Japanese wanted to scrap daylight-saving time, as opposed to 30% who
1243# wanted to keep it.)
1244
1245# From Paul Eggert (2006-03-22):
1246# Shanks & Pottenger write that DST in Japan during those years was as follows:

1252# but the only locations using it (for birth certificates, presumably, since

1254# that for most purposes daylight-saving time was observed; otherwise, what
1255# would have been the point of the 1951 poll?
1256
1257# From Hideyuki Suzuki (1998-11-09):
1258# 'Tokyo' usually stands for the former location of Tokyo Astronomical
1259# Observatory: E 139 44' 40".90 (9h 18m 58s.727), N 35 39' 16".0.
1260# This data is from 'Rika Nenpyou (Chronological Scientific Tables) 1996'
1261# edited by National Astronomical Observatory of Japan....
1262# JST (Japan Standard Time) has been used since 1888-01-01 00:00 (JST).
1263# The law is enacted on 1886-07-07.
1264
1265# From Hideyuki Suzuki (1998-11-16):
1266# The ordinance No. 51 (1886) established "standard time" in Japan,
1267# which stands for the time on E 135 degree.
1268# In the ordinance No. 167 (1895), "standard time" was renamed to "central
1269# standard time".  And the same ordinance also established "western standard
1270# time", which stands for the time on E 120 degree....  But "western standard
1271# time" was abolished in the ordinance No. 529 (1937).  In the ordinance No.
1272# 167, there is no mention regarding for what place western standard time is
1273# standard....
1274#
1275# I wrote "ordinance" above, but I don't know how to translate.
1276# In Japanese it's "chokurei", which means ordinance from emperor.
1277
1278# Shanks & Pottenger claim JST in use since 1896, and that a few
1279# places (e.g. Ishigaki) use +0800; go with Suzuki.  Guess that all
1280# ordinances took effect on Jan 1.

1383# Kazakhstan
1384
1385# From Paul Eggert (1996-11-22):
1386# Andrew Evtichov (1996-04-13) writes that Kazakhstan
1387# stayed in sync with Moscow after 1990, and that Aqtobe (formerly Aktyubinsk)
1388# and Aqtau (formerly Shevchenko) are the largest cities in their zones.
1389# Guess that Aqtau and Aqtobe diverged in 1995, since that's the first time
1390# IATA SSIM mentions a third time zone in Kazakhstan.
1391
1392# From Paul Eggert (2006-03-22):
1393# German Iofis, ELSI, Almaty (2001-10-09) reports that Kazakhstan uses
1394# RussiaAsia rules, instead of switching at 00:00 as the IATA has it.
1395# Go with Shanks & Pottenger, who have them always using RussiaAsia rules.
1396# Also go with the following claims of Shanks & Pottenger:
1397#
1398# - Kazakhstan did not observe DST in 1991.
1399# - Qyzylorda switched from +5:00 to +6:00 on 1992-01-19 02:00.
1400# - Oral switched from +5:00 to +4:00 in spring 1989.
1401
1402# <a href="http://www.kazsociety.org.uk/news/2005/03/30.htm">
1403# From Kazakhstan Embassy's News Bulletin #11 (2005-03-21):
1404# </a>
1405# The Government of Kazakhstan passed a resolution March 15 abolishing
1406# daylight saving time citing lack of economic benefits and health
1407# complications coupled with a decrease in productivity.
1408#
1409# From Branislav Kojic (in Astana) via Gwillim Law (2005-06-28):
1410# ... what happened was that the former Kazakhstan Eastern time zone
1411# was "blended" with the Central zone.  Therefore, Kazakhstan now has
1412# two time zones, and difference between them is one hour.  The zone
1413# closer to UTC is the former Western zone (probably still called the
1414# same), encompassing four provinces in the west: Aqtobe, Atyrau,
1415# Mangghystau, and West Kazakhstan.  The other zone encompasses
1416# everything else....  I guess that would make Kazakhstan time zones
1417# de jure UTC+5 and UTC+6 respectively.

1976
1977# From Amos Shapir (1998-02-15):
1978#
1979# From 1917 until 1948-05-15, all of Palestine, including the parts now
1980# known as the Gaza Strip and the West Bank, was under British rule.
1981# Therefore the rules given for Israel for that period, apply there too...
1982#
1983# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
1984# (except a short occupation by Israel from 1956-11 till 1957-03, but no
1985# time zone was affected then).  It was never formally annexed to Egypt,
1986# though.
1987#
1988# The rest of Palestine was under Jordanian rule at that time, formally
1989# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
1990# the country's previous name of "the Hashemite Kingdom of the
1991# Trans-Jordan").  So the rules for Jordan for that time apply.  Major
1992# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
1993# East Jerusalem.
1994#
1995# Both areas were occupied by Israel in June 1967, but not annexed (except
1996# for East Jerusalem).  They were on Israel time since then; there might
1997# have been a Military Governor's order about time zones, but I'm not aware
1998# of any (such orders may have been issued semi-annually whenever summer
1999# time was in effect, but maybe the legal aspect of time was just neglected).
2000#
2001# The Palestinian Authority was established in 1993, and got hold of most
2002# towns in the West Bank and Gaza by 1995.  I know that in order to
2003# demonstrate...independence, they have been switching to
2004# summer time and back on a different schedule than Israel's, but I don't
2005# know when this was started, or what algorithm is used (most likely the
2006# Jordanian one).
2007#
2008# To summarize, the table should probably look something like that:
2009#
2010# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
2011# ------------+-----------+-----------+-----------+-----------
2012# Israel      | Zion      | Zion      | Zion      | Zion
2013# West bank   | Zion      | Jordan    | Zion      | Jordan
2014# Gaza        | Zion      | Egypt     | Zion      | Jordan
2015#

2017# have one).

2019# From Paul Eggert (2006-03-22):

2021# with Shapir and assume that it observed DST from 1940 through 1947,
2022# and that it used Jordanian rules starting in 1996.
2023# We don't yet need a separate entry for the West Bank, since
2024# the only differences between it and Gaza that we know about
2025# occurred before our cutoff date of 1970.
2026# However, as we get more information, we may need to add entries
2027# for parts of the West Bank as they transitioned from Israel's rules

2042# Holiday havoc
2043# </a> (Jerusalem Post, 1999-04-22) that
2044# the Palestinian National Authority changed to DST on 1999-04-15.
2045# I vaguely recall that they switch back in October (sorry, forgot the source).
2046# For now, let's assume that the spring switch was at 24:00,
2047# and that they switch at 0:00 on the 3rd Fridays of April and October.

2051
2052# From Steffen Thorsen (2005-11-23):
2053# A user from Gaza reported that Gaza made the change early because of
2054# the Ramadan.  Next year Ramadan will be even earlier, so I think
2055# there is a good chance next year's end date will be around two weeks
2056# earlier--the same goes for Jordan.
2057
2058# From Steffen Thorsen (2006-08-17):
2059# I was informed by a user in Bethlehem that in Bethlehem it started the
2060# same day as Israel, and after checking with other users in the area, I
2061# was informed that they started DST one day after Israel.  I was not
2062# able to find any authoritative sources at the time, nor details if
2063# Gaza changed as well, but presumed Gaza to follow the same rules as
2064# the West Bank.

2078
2079# From Paul Eggert (2007-09-20):
2080# My understanding is that Gaza and the West Bank disagree even over when

2082# surprised if they agreed about DST.  But for now, assume they agree.

2305
2306# From K Sethu (2006-04-25):
2307# I think the abbreviation LKT originated from the world of computers at
2308# the time of or subsequent to the time zone changes by SL Government
2309# twice in 1996 and probably SL Government or its standardization
2310# agencies never declared an abbreviation as a national standard.
2311#
2312# I recollect before the recent change the government annoucemments
2313# mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka
2314# Time and no mention was made about the abbreviation.
2315#
2316# If we look at Sri Lanka Department of Government's "Official News
2317# Website of Sri Lanka" ... http://www.news.lk/ we can see that they
2318# use SLT as abbreviation in time stamp at the beginning of each news
2319# item....
2320#
2321# Within Sri Lanka I think LKT is well known among computer users and
2322# adminsitrators.  In my opinion SLT may not be a good choice because the
2323# nation's largest telcom / internet operator Sri Lanka Telcom is well
2324# known by that abbreviation - simply as SLT (there IP domains are
2325# slt.lk and sltnet.lk).
2326#
2327# But if indeed our government has adopted SLT as standard abbreviation
2328# (that we have not known so far) then  it is better that it be used for
2329# all computers.
