17# for recent time zone data is the International Air Transport
18# Association's Standard Schedules Information Manual (IATA SSIM),

237# No they don't. See TIME mag, 1986-02-17 p.52. Even though
238# China is across 4 physical time zones, before Feb 1, 1986 only the
239# Peking (Bejing) time zone was recognized. Since that date, China
240# has two of 'em -- Peking's and Urumqi (named after the capital of

634# From Oscar van Vlijmen (2005-03-30), writing about future

636# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
637# the vernal equinox and that gets so close to 12:00 some local
638# Iranian time that the definition of the correct location needs to be
639# known exactly, amongst other factors. 2157 is even closer:
640# 2157-03-20 08:37:15.5 UT. But the Gregorian year 2025 should give
641# no interpretation problem whatsoever. By the way, another instant
642# in the near future where there will be a discrepancy between
643# arithmetical and astronomical Iranian calendars will be in 2058:
644# vernal equinox on 2058-03-20 09:03:05.9 UT. The Java version of

727# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
728# the U.S. edition) on the Iraqi Kurds contains a paragraph:
729# "The three northern provinces ... switched their clocks this spring and
730# are an hour ahead of Baghdad."
731#
732# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
733# In the past, some Kurdish nationalists, as a protest to the Iraqi
734# Government, did not adhere to daylight saving time. They referred
735# to daylight saving as Saddam time. But, as of today, the time zone
736# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
737#
738# So we'll ignore the Economist's claim.

778# From Ephraim Silverberg (2001-01-11):
779#
780# I coined "IST/IDT" circa 1988. Until then there were three
781# different abbreviations in use:
782#
783# JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
784# IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
785# EEST Eastern Europe Standard Time [used by almost everyone else]
786#
787# Since timezones should be called by country and not capital cities,
788# I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
789# EEST was equally unacceptable. Since "zonal" was not compatible with
790# any other timezone abbreviation, I felt that 'IST' was the way to go
791# and, indeed, it has received almost universal acceptance in timezone
792# settings in Israeli computers.
793#
794# In any case, I am happy to share timezone abbreviations with India,
795# high on my favorite-country list (and not only because my wife's
796# family is from India).

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

1708# The rest of Palestine was under Jordanian rule at that time, formally
1709# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
1710# the country's previous name of "the Hashemite Kingdom of the
1711# Trans-Jordan"). So the rules for Jordan for that time apply. Major
1712# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
1713# East Jerusalem.
1714#
1715# Both areas were occupied by Israel in June 1967, but not annexed (except
1716# for East Jerusalem). They were on Israel time since then; there might
1717# have been a Military Governor's order about time zones, but I'm not aware
1718# of any (such orders may have been issued semi-annually whenever summer
1719# time was in effect, but maybe the legal aspect of time was just neglected).
1720#
1721# The Palestinian Authority was established in 1993, and got hold of most
1722# towns in the West Bank and Gaza by 1995. I know that in order to
1723# demonstrate...independence, they have been switching to
1724# summer time and back on a different schedule than Israel's, but I don't
1725# know when this was started, or what algorithm is used (most likely the
1726# Jordanian one).
1727#
1728# To summarize, the table should probably look something like that:
1729#
1730# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
1731# ------------+-----------+-----------+-----------+-----------
1732# Israel | Zion | Zion | Zion | Zion
1733# West bank | Zion | Jordan | Zion | Jordan
1734# Gaza | Zion | Egypt | Zion | Jordan
1735#
1736# I guess more info may be available from the PA's web page (if/when they
1737# have one).

1964# I think the abbreviation LKT originated from the world of computers at

1966# twice in 1996 and probably SL Government or its standardization
1967# agencies never declared an abbreviation as a national standard.
1968#
1969# I recollect before the recent change the government annoucemments
1970# mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka
1971# Time and no mention was made about the abbreviation.
1972#
1973# If we look at Sri Lanka Department of Government's "Official News
1974# Website of Sri Lanka" ... http://www.news.lk/ we can see that they
1975# use SLT as abbreviation in time stamp at the beginning of each news
1976# item....
1977#
1978# Within Sri Lanka I think LKT is well known among computer users and
1979# adminsitrators. In my opinion SLT may not be a good choice because the
1980# nation's largest telcom / internet operator Sri Lanka Telcom is well
1981# known by that abbreviation - simply as SLT (there IP domains are
1982# slt.lk and sltnet.lk).

2052# The sister center ICARDA of my work CIMMYT is confirming that Syria DST will
2053# not take place 1.st November at 0:00 o'clock but 1.st November at 24:00 or
2054# rather Midnight between Thursday and Friday. This does make more sence than
2055# having it between Wednesday and Thursday (two workdays in Syria) since the
2056# weekend in Syria is not Saturday and Sunday, but Friday and Saturday. So now
2057# it is implemented at midnight of the last workday before weekend...

2094# Since Syria is two hours east of UTC, the 2200 and 2100 transition times

2099# coding that involves either using a "Mar Fri>=29" construct that old time zone
2100# compilers can't handle or having multiple Rules (a la Israel).
2101# For now, use "Apr Fri>=1", and go with IATA on a uniform Sep 30 end.
