9# A good source for time zone historical data outside the U.S. is
10# Thomas G. Shanks, The International Atlas (3rd edition),
11# San Diego: ACS Publications, Inc. (1991).
12# Except where otherwise noted, it is the source for the data below.

14# Gwillim Law <LAW@encmail.encompass.com> writes that a good source
15# for recent time zone data is the International Air Transport
16# Association's Standard Schedules Information Manual (IATA SSIM),
17# published semiannually. Law sent in several helpful summaries
18# of the IATA's data after 1990.
19#
20# Except where otherwise noted, Shanks is the source for entries through 1990,
21# and IATA SSIM is the source for entries after 1990.
22#
28f540f4
RM
23# Another source occasionally used is Edward W. Whitman, World Time Differences,
24# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
25# I found in the UCLA library.
26#
27# A reliable and entertaining source about time zones is
28# Derek Howse, Greenwich time and the discovery of the longitude,
29# Oxford University Press (1980).
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.

81# From Paul Eggert (1996-05-04):
82# Shanks has Yerevan switching to 3:00 (with Russian DST) in spring 1991,
83# but usno1995 has Armenia at 4:00 (with DST), and Edgar Der-Danieliantz
84# <edd@AIC.NET> reported today that Yerevan probably won't use DST this year,
85# though it did use DST in 1995. We guess Yerevan stayed in sync with Moscow
86# between 1990 and 1995, but stopped using DST in 1996.

164# China is across 4 physical time zones, before Feb 1, 1986 only the

515# there is a "supposed" set of rules which is subject to change depending
516# on the party the Minister of Interior, the size of the coalition
517# government, the phase of the moon and the direction of the wind. Hence,
518# changes may need to be made on a semi-annual basis. One thing is entrenched
a5570f62 519# in law, however: that there must be at least 150 days of daylight savings

520# time annually. Ever since 1993, the change to daylight savings time is
521# on a Thursday night from midnight IST to 1 a.m IDT. The change back to
522# standard time is on a Saturday night from midnight daylight savings time
72d8cdf0 523# to 11 p.m. standard time. 1996 is an exception to this rule where the
4cca6b86 524# change back to standard time took place on Sunday night instead of Saturday

830# From Amos Shapir <amos@nsof.co.il> (1998-02-15):
831#
832# From 1917 until 1948-05-15, all of Palestine, including the parts now
833# known as the Gaza Strip and the West Bank, was under British rule.
834# Therefore the rules given for Israel for that period, apply there too...
835#
836# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
837# (except a short occupation by Israel from 1956-11 till 1957-03, but no
838# time zone was affected then). It was never formally annexed to Egypt,
839# though.
840#
841# The rest of Palestine was under Jordanian rule at that time, formally
842# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
843# the country's previous name of "the Hashemite Kingdom of the
844# Trans-Jordan"). So the rules for Jordan for that time apply. Major
845# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
846# East Jerusalem.
847#
848# Both areas were occupied by Israel in June 1967, but not annexed (except
849# for East Jerusalem). They were on Israel time since then; there might
850# have been a Military Governor's order about time zones, but I'm not aware
851# of any (such orders may have been issued semi-annually whenever summer
852# time was in effect, but maybe the legal aspect of time was just neglected).
853#
854# The Palestinian Authority was established in 1993, and got hold of most
855# towns in the West Bank and Gaza by 1995. I know that in order to
856# demonstrate...independence, they have been switching to
857# summer time and back on a different schedule than Israel's, but I don't
858# know when this was started, or what algorithm is used (most likely the
859# Jordanian one).
860#
861# To summarize, the table should probably look something like that:
862#
863# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
864# ------------+-----------+-----------+-----------+-----------
865# Israel | Zion | Zion | Zion | Zion
866# West bank | Zion | Jordan | Zion | Jordan
867# Gaza | Zion | Egypt | Zion | Jordan
868#
869# I guess more info may be available from the PA's web page (if/when they
870# have one).
871
872# From Paul Eggert (1998-02-25):
873# Shanks writes that Gaza did not observe DST until 1957, but we'll go
874# with Shapir and assume that it observed DST from 1940 through 1947,
875# and that it used Jordanian rules starting in 1996.
876# We don't yet need a separate entry for the West Bank, since
877# the only differences between it and Gaza that we know about
878# occurred before our cutoff date of 1970.
879# However, as we get more information, we may need to add entries
880# for parts of the West Bank as they transitioned from Israel's rules
881# to Palestine's rules. If you have more info about this, please
882# send it to tz@elsie.nci.nih.gov for incorporation into future editions.
