3 # This data is by no means authoritative; if you think you know better,
4 # go ahead and edit the file (and please send any changes to
5 # tz@elsie.nci.nih.gov for general use in the future).
7 # From Paul Eggert <eggert@twinsun.com> (1996-11-22):
8 #
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.
13 #
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 #
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.

84 # <edd@AIC.NET> reported today that Yerevan probably won't use DST this year,

157 # China
159 # From Guy Harris:
160 # People's Republic of China. Yes, they really have only one time zone.
162 # From Bob Devine (1988-01-28):
163 # No they don't. See TIME mag, 1986-02-17 p.52. Even though
164 # China is across 4 physical time zones, before Feb 1, 1986 only the
165 # Peking (Bejing) time zone was recognized. Since that date, China
166 # has two of 'em -- Peking's and Urumqi (named after the capital of
167 # the Xinjiang Uighur Autonomous Region). I don't know about DST for it.
168 #
169 # . . .I just deleted the DST table and this editor makes it too
170 # painful to suck in another copy.. So, here is what I have for
171 # DST start/end dates for Peking's time zone (info from AP):
172 #
173 # 1986 May 4 - Sept 14
174 # 1987 mid-April - ??
176 # From U. S. Naval Observatory (1989-01-19):
177 # CHINA 8 H AHEAD OF UTC ALL OF CHINA, INCL TAIWAN
178 # CHINA 9 H AHEAD OF UTC APR 17 - SEP 10
180 # From Paul Eggert <eggert@twinsun.com> (1995-12-19):
181 # Shanks writes that China has had a single time zone since 1980 May 1,
182 # observing summer DST from 1986 through 1991; this contradicts Devine's
183 # note about Time magazine, though apparently _something_ happened in 1986.
184 # Go with Shanks for now. I made up names for the other pre-1980 time zones.

510 # (1997-03-04 and 1998-03-16):
512 # According to the Office of the Secretary General of the Ministry of
513 # Interior, there is NO set rule for Daylight-Savings/Standard time changes.
514 # Each year they decide anew what havoc to wreak on the country. However,
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
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
523 # to 11 p.m. standard time. 1996 is an exception to this rule where the
524 # change back to standard time took place on Sunday night instead of Saturday
525 # night to avoid conflicts with the Jewish New Year.

828 # Palestine
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).
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.
884 # From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time,
885 # forwarded by Ephraim Silverberg:
886 #
887 # Despite the fact that Israel changed over to daylight savings time
888 # last week, the PLO Authority (PA) has decided not to turn its clocks
889 # one-hour forward at this time. As a sign of independence from Israeli rule,
890 # the PA has decided to implement DST in April.
892 # These rules for Egypt are stolen from the `africa' file.
