10# From Paul Eggert (2006-03-22):
11#
12# A good source for time zone historical data outside the U.S. is
13# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
14# San Diego: ACS Publications, Inc. (2003).
15#
16# Gwillim Law writes that a good source
17# for recent time zone data is the International Air Transport
18# Association's Standard Schedules Information Manual (IATA SSIM),
19# published semiannually. Law sent in several helpful summaries
20# of the IATA's data after 1990.
21#
22# Except where otherwise noted, Shanks & Pottenger is the source for
23# entries through 1990, and IATA SSIM is the source for entries afterwards.
24#
25# Another source occasionally used is Edward W. Whitman, World Time Differences,
26# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
27# I found in the UCLA library.
28#
29# A reliable and entertaining source about time zones is
30# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).

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

224# China
225
226# From Guy Harris:
227# People's Republic of China. Yes, they really have only one time zone.
228
229# From Bob Devine (1988-01-28):
230# No they don't. See TIME mag, 1986-02-17 p.52. Even though
231# China is across 4 physical time zones, before Feb 1, 1986 only the
232# Peking (Bejing) time zone was recognized. Since that date, China
233# has two of 'em -- Peking's and Urumqi (named after the capital of
234# the Xinjiang Uyghur Autonomous Region). I don't know about DST for it.
235#
236# . . .I just deleted the DST table and this editor makes it too
237# painful to suck in another copy.. So, here is what I have for
238# DST start/end dates for Peking's time zone (info from AP):
239#
240# 1986 May 4 - Sept 14
241# 1987 mid-April - ??
242
243# From U. S. Naval Observatory (1989-01-19):
244# CHINA 8 H AHEAD OF UTC ALL OF CHINA, INCL TAIWAN
245# CHINA 9 H AHEAD OF UTC APR 17 - SEP 10
246
247# From Paul Eggert (2006-03-22):
248# Shanks & Pottenger write that China (except for Hong Kong and Macau)
249# has had a single time zone since 1980 May 1, observing summer DST
250# from 1986 through 1991; this contradicts Devine's
251# note about Time magazine, though apparently _something_ happened in 1986.
252# Go with Shanks & Pottenger for now. I made up names for the other

264# From Anthony Fok (2001-12-20):
265# BTW, I did some research on-line and found some info regarding these five
266# historic timezones from some Taiwan websites. And yes, there are official
267# Chinese names for these locales (before 1949).
268#
269# From Jesper Norgaard Welen (2006-07-14):
270# I have investigated the timezones around 1970 on the
271# http://www.astro.com/atlas site [with provinces and county
272# boundaries summarized below].... A few other exceptions were two
273# counties on the Sichuan side of the Xizang-Sichuan border,
274# counties Dege and Baiyu which lies on the Sichuan side and are
275# therefore supposed to be GMT+7, Xizang region being GMT+6, but Dege
276# county is GMT+8 according to astro.com while Baiyu county is GMT+6
277# (could be true), for the moment I am assuming that those two
278# counties are mistakes in the astro.com data.
279
280# From Paul Eggert (2008-02-11):
281# I just now checked Google News for western news sources that talk
282# about China's single time zone, and couldn't find anything before 1986
283# talking about China being in one time zone. (That article was: Jim
284# Mann, "A clumsy embrace for another western custom: China on daylight
285# time--sort of", Los Angeles Times, 1986-05-05. By the way, this
286# article confirms the tz database's data claiming that China began
287# observing daylight saving time in 1986.
288#
289# From Thomas S. Mullaney (2008-02-11):
290# I think you're combining two subjects that need to treated
291# separately: daylight savings (which, you're correct, wasn't
292# implemented until the 1980s) and the unified time zone centered near
293# Beijing (which was implemented in 1949). Briefly, there was also a
294# "Lhasa Time" in Tibet and "Urumqi Time" in Xinjiang. The first was
295# ceased, and the second eventually recognized (again, in the 1980s).
296#
297# From Paul Eggert (2008-06-30):
298# There seems to be a good chance China switched to a single time zone in 1949
299# rather than in 1980 as Shanks & Pottenger have it, but we don't have a
300# reliable documentary source saying so yet, so for now we still go with

438# Georgia
439# From Paul Eggert (1994-11-19):
440# Today's _Economist_ (p 60) reports that Georgia moved its clocks forward
441# an hour recently, due to a law proposed by Zurab Murvanidze,
442# an MP who went on a hunger strike for 11 days to force discussion about it!
443# We have no details, but we'll guess they didn't move the clocks back in fall.
444#
445# From Mathew Englander, quoting AP (1996-10-23 13:05-04):
446# Instead of putting back clocks at the end of October, Georgia
447# will stay on daylight savings time this winter to save energy,
448# President Eduard Shevardnadze decreed Wednesday.
449#
450# From the BBC via Joseph S. Myers (2004-06-27):
451#
452# Georgia moved closer to Western Europe on Sunday... The former Soviet
453# republic has changed its time zone back to that of Moscow. As a result it
454# is now just four hours ahead of Greenwich Mean Time, rather than five hours
455# ahead. The switch was decreed by the pro-Western president of Georgia,
456# Mikhail Saakashvili, who said the change was partly prompted by the process
457# of integration into Europe.
458
459# From Teimuraz Abashidze (2005-11-07):
460# Government of Georgia ... decided to NOT CHANGE daylight savings time on
461# [Oct.] 30, as it was done before during last more than 10 years.
462# Currently, we are in fact GMT +4:00, as before 30 October it was GMT
463# +3:00.... The problem is, there is NO FORMAL LAW or governmental document
464# about it. As far as I can find, I was told, that there is no document,
465# because we just DIDN'T ISSUE document about switching to winter time....
466# I don't know what can be done, especially knowing that some years ago our
467# DST rules where changed THREE TIMES during one month.

490# East Timor may be late for its millennium
491# </a> (1999-12-26/31):
492# Portugal tried to change the time forward in 1974 because the sun

537#
538# From Paul Eggert (2007-03-10):
539# Here is another correction to Shanks & Pottenger.
540# JohnTWB writes that Japanese forces did not surrender control in

542# other formal surrender ceremonies were September 9, 11, and 13, plus

584# From Roozbeh Pournader (2003-03-15):
585# This is an English translation of what I just found (originally in Persian).
586# The Gregorian dates in brackets are mine:
587#
588# Official Newspaper No. 13548-1370/6/25 [1991-09-16]
589# No. 16760/T233 H 1370/6/10 [1991-09-01]
590#
591# The Rule About Change of the Official Time of the Country
592#
593# The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14],
594# based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13]
595# of the Country's Organization for Official and Employment Affairs,
596# and referring to the law for equating the working hours of workers
597# and officers in the whole country dated 1359/4/23 [1980-07-14], and
598# for synchronizing the official times of the country, agreed that:
599#
600# The official time of the country will should move forward one hour
601# at the 24[:00] hours of the first day of Farvardin and should return
602# to its previous state at the 24[:00] hours of the 30th day of
603# Shahrivar.
604#
605# First Deputy to the President - Hassan Habibi
606#
607# From personal experience, that agrees with what has been followed
608# for at least the last 5 years. Before that, for a few years, the
609# date used was the first Thursday night of Farvardin and the last
610# Thursday night of Shahrivar, but I can't give exact dates....
611# I have also changed the abbreviations to what is considered correct
612# here in Iran, IRST for regular time and IRDT for daylight saving time.
613#
614# From Roozbeh Pournader (2005-04-05):
615# The text of the Iranian law, in effect since 1925, clearly mentions
616# that the true solar year is the measure, and there is no arithmetic
617# leap year calculation involved. There has never been any serious
618# plan to change that law....
619#
620# From Paul Eggert (2006-03-22):
621# Go with Shanks & Pottenger before Sept. 1991, and with Pournader thereafter.
622# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,
623# stopping after 2037 when 32-bit time_t's overflow.
624# That cal-persia used Birashk's approximation, which disagrees with the solar
625# calendar predictions for the year 2025, so I corrected those dates by hand.
626#
627# From Oscar van Vlijmen (2005-03-30), writing about future
628# discrepancies between cal-persia and the Iranian calendar:
629# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
630# the vernal equinox and that gets so close to 12:00 some local
631# Iranian time that the definition of the correct location needs to be
632# known exactly, amongst other factors. 2157 is even closer:
633# 2157-03-20 08:37:15.5 UT. But the Gregorian year 2025 should give
634# no interpretation problem whatsoever. By the way, another instant
635# in the near future where there will be a discrepancy between
636# arithmetical and astronomical Iranian calendars will be in 2058:
637# vernal equinox on 2058-03-20 09:03:05.9 UT. The Java version of
638# Reingold's/Dershowitz' calculator gives correctly the Gregorian date
639# 2058-03-21 for 1 Farvardin 1437 (astronomical).
640#
641# From Steffen Thorsen (2006-03-22):
642# Several of my users have reported that Iran will not observe DST anymore:
643# http://www.irna.ir/en/news/view/line-17/0603193812164948.htm
644#
645# From Reuters (2007-09-16), with a heads-up from Jesper Norgaard Welen:
646# ... the Guardian Council ... approved a law on Sunday to re-introduce
647# daylight saving time ...
648# http://uk.reuters.com/article/oilRpt/idUKBLA65048420070916
649#
650# From Roozbeh Pournader (2007-11-05):
651# This is quoted from Official Gazette of the Islamic Republic of
652# Iran, Volume 63, Number 18242, dated Tuesday 1386/6/24
653# [2007-10-16]. I am doing the best translation I can:...
654# The official time of the country will be moved forward for one hour
655# on the 24 hours of the first day of the month of Farvardin and will

719# From Jonathan Lennox (2000-06-12):
720# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
721# the U.S. edition) on the Iraqi Kurds contains a paragraph:
722# "The three northern provinces ... switched their clocks this spring and
723# are an hour ahead of Baghdad."
724#
725# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
726# In the past, some Kurdish nationalists, as a protest to the Iraqi
727# Government, did not adhere to daylight saving time. They referred
728# to daylight saving as Saddam time. But, as of today, the time zone
729# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
730#
731# So we'll ignore the Economist's claim.

771# From Ephraim Silverberg (2001-01-11):
772#
773# I coined "IST/IDT" circa 1988. Until then there were three
774# different abbreviations in use:
775#
776# JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
777# IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
778# EEST Eastern Europe Standard Time [used by almost everyone else]
779#
780# Since timezones should be called by country and not capital cities,
781# I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
782# EEST was equally unacceptable. Since "zonal" was not compatible with
783# any other timezone abbreviation, I felt that 'IST' was the way to go
784# and, indeed, it has received almost universal acceptance in timezone
785# settings in Israeli computers.
786#
787# In any case, I am happy to share timezone abbreviations with India,
788# high on my favorite-country list (and not only because my wife's
789# family is from India).

834# From Ephraim Silverberg
835# (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17, 2000-07-25, 2004-12-22,
836# and 2005-02-17):
837
838# According to the Office of the Secretary General of the Ministry of
839# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
840# One thing is entrenched in law, however: that there must be at least 150
841# days of daylight savings time annually. From 1993-1998, the change to
842# daylight savings time was on a Friday morning from midnight IST to
843# 1 a.m IDT; up until 1998, the change back to standard time was on a
844# Saturday night from midnight daylight savings time to 11 p.m. standard
845# time. 1996 is an exception to this rule where the change back to standard
846# time took place on Sunday night instead of Saturday night to avoid
847# conflicts with the Jewish New Year. In 1999, the change to
848# daylight savings time was still on a Friday morning but from
849# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
850# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
851# 1999 only. In the year 2000, the change to daylight savings time was
852# similar to 1999, but although the change back will be on a Friday, it
853# will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
854# changes to/from will take place at 1 a.m. old time, but now there is no
855# rule as to what day of the week it will take place in as the start date
856# (except in 2003) is the night after the Passover Seder (i.e. the eve
857# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
858# (except in 2002) is three nights before Yom Kippur [Day of Atonement]
859# (the eve of the 7th of Tishrei in the lunar Hebrew calendar).

1014# From Paul Eggert (1995-03-06):
1015# Today's _Asahi Evening News_ (page 4) reports that Japan had
1016# daylight saving between 1948 and 1951, but ``the system was discontinued
1017# because the public believed it would lead to longer working hours.''
1018
1019# From Mayumi Negishi in the 2005-08-10 Japan Times
1020# <http://www.japantimes.co.jp/cgi-bin/getarticle.pl5?nn20050810f2.htm>:
1021# Occupation authorities imposed daylight-saving time on Japan on
1022# [1948-05-01].... But lack of prior debate and the execution of
1023# daylight-saving time just three days after the bill was passed generated
1024# deep hatred of the concept.... The Diet unceremoniously passed a bill to
1025# dump the unpopular system in October 1951, less than a month after the San
1026# Francisco Peace Treaty was signed. (A government poll in 1951 showed 53%
1027# of the Japanese wanted to scrap daylight-saving time, as opposed to 30% who
1028# wanted to keep it.)
1029

1042# From Hideyuki Suzuki (1998-11-09):
1043# 'Tokyo' usually stands for the former location of Tokyo Astronomical

1045# This data is from 'Rika Nenpyou (Chronological Scientific Tables) 1996'

1050# From Hideyuki Suzuki (1998-11-16):
1051# The ordinance No. 51 (1886) established "standard time" in Japan,
1052# which stands for the time on E 135 degree.
1053# In the ordinance No. 167 (1895), "standard time" was renamed to "central
1054# standard time". And the same ordinance also established "western standard
1055# time", which stands for the time on E 120 degree.... But "western standard
1056# time" was abolished in the ordinance No. 529 (1937). In the ordinance No.
1057# 167, there is no mention regarding for what place western standard time is
1058# standard....

1060# I wrote "ordinance" above, but I don't know how to translate.
1061# In Japanese it's "chokurei", which means ordinance from emperor.

1063# Shanks & Pottenger claim JST in use since 1896, and that a few

1170# From Paul Eggert (1996-11-22):
1171# Andrew Evtichov (1996-04-13) writes that Kazakhstan
1172# stayed in sync with Moscow after 1990, and that Aqtobe (formerly Aktyubinsk)
1173# and Aqtau (formerly Shevchenko) are the largest cities in their zones.
1174# Guess that Aqtau and Aqtobe diverged in 1995, since that's the first time
1175# IATA SSIM mentions a third time zone in Kazakhstan.
1176
1177# From Paul Eggert (2006-03-22):
1178# German Iofis, ELSI, Almaty (2001-10-09) reports that Kazakhstan uses
1179# RussiaAsia rules, instead of switching at 00:00 as the IATA has it.
1180# Go with Shanks & Pottenger, who have them always using RussiaAsia rules.
1181# Also go with the following claims of Shanks & Pottenger:
1182#
1183# - Kazakhstan did not observe DST in 1991.
1184# - Qyzylorda switched from +5:00 to +6:00 on 1992-01-19 02:00.

1190# The Government of Kazakhstan passed a resolution March 15 abolishing

1194# From Branislav Kojic (in Astana) via Gwillim Law (2005-06-28):
1195# ... what happened was that the former Kazakhstan Eastern time zone
1196# was "blended" with the Central zone. Therefore, Kazakhstan now has
1197# two time zones, and difference between them is one hour. The zone
1198# closer to UTC is the former Western zone (probably still called the
1199# same), encompassing four provinces in the west: Aqtobe, Atyrau,
1200# Mangghystau, and West Kazakhstan. The other zone encompasses

1689
1690# From Amos Shapir (1998-02-15):
1691#
1692# From 1917 until 1948-05-15, all of Palestine, including the parts now
1693# known as the Gaza Strip and the West Bank, was under British rule.
1694# Therefore the rules given for Israel for that period, apply there too...
1695#
1696# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
1697# (except a short occupation by Israel from 1956-11 till 1957-03, but no
1698# time zone was affected then). It was never formally annexed to Egypt,
1699# though.
1700#
1701# The rest of Palestine was under Jordanian rule at that time, formally
1702# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
1703# the country's previous name of "the Hashemite Kingdom of the
1704# Trans-Jordan"). So the rules for Jordan for that time apply. Major
1705# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
1706# East Jerusalem.
1707#
1708# Both areas were occupied by Israel in June 1967, but not annexed (except
1709# for East Jerusalem). They were on Israel time since then; there might
1710# have been a Military Governor's order about time zones, but I'm not aware
1711# of any (such orders may have been issued semi-annually whenever summer
1712# time was in effect, but maybe the legal aspect of time was just neglected).
1713#
1714# The Palestinian Authority was established in 1993, and got hold of most
1715# towns in the West Bank and Gaza by 1995. I know that in order to
1716# demonstrate...independence, they have been switching to
1717# summer time and back on a different schedule than Israel's, but I don't
1718# know when this was started, or what algorithm is used (most likely the
1719# Jordanian one).
1720#
1721# To summarize, the table should probably look something like that:
1722#
1723# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
1724# ------------+-----------+-----------+-----------+-----------
1725# Israel | Zion | Zion | Zion | Zion
1726# West bank | Zion | Jordan | Zion | Jordan
1727# Gaza | Zion | Egypt | Zion | Jordan
1728#
1729# I guess more info may be available from the PA's web page (if/when they
1730# have one).
1731
1732# From Paul Eggert (2006-03-22):
1733# Shanks & Pottenger write that Gaza did not observe DST until 1957, but go
1734# with Shapir and assume that it observed DST from 1940 through 1947,
1735# and that it used Jordanian rules starting in 1996.
1736# We don't yet need a separate entry for the West Bank, since
1737# the only differences between it and Gaza that we know about
1738# occurred before our cutoff date of 1970.
1739# However, as we get more information, we may need to add entries
1740# for parts of the West Bank as they transitioned from Israel's rules
1741# to Palestine's rules. If you have more info about this, please
1742# send it to tz@elsie.nci.nih.gov for incorporation into future editions.
1743
1744# From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time,

1747# Despite the fact that Israel changed over to daylight savings time
1748# last week, the PLO Authority (PA) has decided not to turn its clocks

1949# [The Tamil Tigers] never accepted the original 1996 time change and simply
1950# kept their clocks set five and a half hours ahead of Greenwich Mean
1951# Time (GMT), in line with neighbor India.
1952# From Paul Eggert (2006-04-18):
1953# People who live in regions under Tamil control can use [TZ='Asia/Kolkata'],
1954# as that zone has agreed with the Tamil areas since our cutoff date of 1970.
1955
1956# From K Sethu (2006-04-25):
1957# I think the abbreviation LKT originated from the world of computers at
1958# the time of or subsequent to the time zone changes by SL Government
1959# twice in 1996 and probably SL Government or its standardization
1960# agencies never declared an abbreviation as a national standard.
1961#
1962# I recollect before the recent change the government annoucemments
1963# mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka
1964# Time and no mention was made about the abbreviation.
1965#
1966# If we look at Sri Lanka Department of Government's "Official News
1967# Website of Sri Lanka" ... http://www.news.lk/ we can see that they
1968# use SLT as abbreviation in time stamp at the beginning of each news
1969# item....
1970#
1971# Within Sri Lanka I think LKT is well known among computer users and
1972# adminsitrators. In my opinion SLT may not be a good choice because the
1973# nation's largest telcom / internet operator Sri Lanka Telcom is well
1974# known by that abbreviation - simply as SLT (there IP domains are
1975# slt.lk and sltnet.lk).
1976#
1977# But if indeed our government has adopted SLT as standard abbreviation
1978# (that we have not known so far) then it is better that it be used for
1979# all computers.
1980
1981# From Paul Eggert (2006-04-25):
