226# From Bob Devine (1988-01-28):
227# No they don't. See TIME mag, 1986-02-17 p.52. Even though
228# China is across 4 physical time zones, before Feb 1, 1986 only the
229# Peking (Bejing) time zone was recognized. Since that date, China
230# has two of 'em -- Peking's and Urumqi (named after the capital of

233# . . .I just deleted the DST table and this editor makes it too

278# I just now checked Google News for western news sources that talk

280# talking about China being in one time zone. (That article was: Jim
281# Mann, "A clumsy embrace for another western custom: China on daylight
282# time--sort of", Los Angeles Times, 1986-05-05. By the way, this
283# article confirms the tz database's data claiming that China began
284# observing daylight saving time in 1986.
285#
286# From Thomas S. Mullaney (2008-02-11):
287# I think you're combining two subjects that need to treated
288# separately: daylight savings (which, you're correct, wasn't
289# implemented until the 1980s) and the unified time zone centered near
290# Beijing (which was implemented in 1949). Briefly, there was also a
291# "Lhasa Time" in Tibet and "Urumqi Time" in Xinjiang. The first was
292# ceased, and the second eventually recognized (again, in the 1980s).
293#
294# From Paul Eggert (2008-06-30):
295# There seems to be a good chance China switched to a single time zone in 1949
296# rather than in 1980 as Shanks & Pottenger have it, but we don't have a

623#
624# From Oscar van Vlijmen (2005-03-30), writing about future
625# discrepancies between cal-persia and the Iranian calendar:
626# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
627# the vernal equinox and that gets so close to 12:00 some local
628# Iranian time that the definition of the correct location needs to be
629# known exactly, amongst other factors. 2157 is even closer:
630# 2157-03-20 08:37:15.5 UT. But the Gregorian year 2025 should give
631# no interpretation problem whatsoever. By the way, another instant
632# in the near future where there will be a discrepancy between
633# arithmetical and astronomical Iranian calendars will be in 2058:
634# vernal equinox on 2058-03-20 09:03:05.9 UT. The Java version of

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

768# From Ephraim Silverberg (2001-01-11):
769#
770# I coined "IST/IDT" circa 1988. Until then there were three
771# different abbreviations in use:
772#
773# JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
774# IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
775# EEST Eastern Europe Standard Time [used by almost everyone else]
776#
777# Since timezones should be called by country and not capital cities,
778# I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
779# EEST was equally unacceptable. Since "zonal" was not compatible with
780# any other timezone abbreviation, I felt that 'IST' was the way to go
781# and, indeed, it has received almost universal acceptance in timezone
782# settings in Israeli computers.
783#
784# In any case, I am happy to share timezone abbreviations with India,
785# high on my favorite-country list (and not only because my wife's
786# family is from India).

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

1041# Observatory: E 139 44' 40".90 (9h 18m 58s.727), N 35 39' 16".0.

1047# From Hideyuki Suzuki (1998-11-16):
1048# The ordinance No. 51 (1886) established "standard time" in Japan,
1049# which stands for the time on E 135 degree.
1050# In the ordinance No. 167 (1895), "standard time" was renamed to "central
1051# standard time". And the same ordinance also established "western standard
1052# time", which stands for the time on E 120 degree.... But "western standard
1053# time" was abolished in the ordinance No. 529 (1937). In the ordinance No.
1054# 167, there is no mention regarding for what place western standard time is
1055# standard....
1056#
1057# I wrote "ordinance" above, but I don't know how to translate.
1058# In Japanese it's "chokurei", which means ordinance from emperor.

1688#
1689# From 1917 until 1948-05-15, all of Palestine, including the parts now
1690# known as the Gaza Strip and the West Bank, was under British rule.
1691# Therefore the rules given for Israel for that period, apply there too...
1692#
1693# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
1694# (except a short occupation by Israel from 1956-11 till 1957-03, but no
1695# time zone was affected then). It was never formally annexed to Egypt,
1696# though.
1697#
1698# The rest of Palestine was under Jordanian rule at that time, formally
1699# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
1700# the country's previous name of "the Hashemite Kingdom of the
1701# Trans-Jordan"). So the rules for Jordan for that time apply. Major
1702# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
1703# East Jerusalem.
1704#
1705# Both areas were occupied by Israel in June 1967, but not annexed (except
1706# for East Jerusalem). They were on Israel time since then; there might
1707# have been a Military Governor's order about time zones, but I'm not aware
1708# of any (such orders may have been issued semi-annually whenever summer
1709# time was in effect, but maybe the legal aspect of time was just neglected).
1710#
1711# The Palestinian Authority was established in 1993, and got hold of most
1712# towns in the West Bank and Gaza by 1995. I know that in order to
1713# demonstrate...independence, they have been switching to
1714# summer time and back on a different schedule than Israel's, but I don't
1715# know when this was started, or what algorithm is used (most likely the
1716# Jordanian one).
1717#

1953# From K Sethu (2006-04-25):
1954# I think the abbreviation LKT originated from the world of computers at

1956# twice in 1996 and probably SL Government or its standardization
1957# agencies never declared an abbreviation as a national standard.
1958#
1959# I recollect before the recent change the government annoucemments
1960# mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka
1961# Time and no mention was made about the abbreviation.
1962#
1963# If we look at Sri Lanka Department of Government's "Official News
1964# Website of Sri Lanka" ... http://www.news.lk/ we can see that they
1965# use SLT as abbreviation in time stamp at the beginning of each news
1966# item....
1967#
1968# Within Sri Lanka I think LKT is well known among computer users and
1969# adminsitrators. In my opinion SLT may not be a good choice because the
1970# nation's largest telcom / internet operator Sri Lanka Telcom is well
1971# known by that abbreviation - simply as SLT (there IP domains are
1972# slt.lk and sltnet.lk).
1973#
1974# But if indeed our government has adopted SLT as standard abbreviation
1975# (that we have not known so far) then it is better that it be used for
1976# all computers.

2065# For everyone's info, I saw an IATA time zone change for [Syria] for
2066# this month (March 2008) in the last day or so...This is the data IATA
2067# are now using:

2078# Agency (SANA)...
2079# <a href="http://www.sana.sy/eng/21/2008/03/11/165173.htm">
2080# http://www.sana.sy/eng/21/2008/03/11/165173.htm
2081# </a>...which reads (in part) "The Cabinet approved the suggestion of the
2082# Ministry of Electricity to begin daylight savings time on Friday April
2083# 4th, advancing clocks one hour ahead on midnight of Thursday April 3rd."
2084# Since Syria is two hours east of UTC, the 2200 and 2100 transition times
2085# shown above match up with midnight in Syria.
2086
2087# From Arthur David Olson (2008-03-18):
2088# My buest guess at a Syrian rule is "the Friday nearest April 1";
2089# coding that involves either using a "Mar Fri>=29" construct that old time zone
2090# compilers can't handle or having multiple Rules (a la Israel).
2091# For now, use "Apr Fri>=1", and go with IATA on a uniform Sep 30 end.
