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

7 # From Paul Eggert <eggert@twinsun.com> (1999-03-22):
8 #
9 # A good source for time zone historical data outside the U.S. is
10 # Thomas G. Shanks, The International Atlas (4th edition),
11 # San Diego: ACS Publications, Inc. (1995).
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 longitude, Antique Collectors Club (1997).

30 # I invented the abbreviations marked `*' in the following table;

80 # Armenia
81 # From Paul Eggert (1998-??-??):
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 (1996-05-04) that Yerevan probably wouldn't use DST
85 # in 1996, though it did use DST in 1995. IATA SSIM (1991/1998) reports that
86 # Armenia switched from 3:00 to 4:00 in 1998 and observed DST after 1991,
87 # but started switching at 3:00s in 1998.
88 # What a mess! We guess Yerevan DST stayed in sync with Moscow between 1990
89 # and 1995, did not use DST in 1996, and started using DST again in 1997.

166 # From Guy Harris:
167 # People's Republic of China. Yes, they really have only one time zone.
169 # From Bob Devine (1988-01-28):
170 # No they don't. See TIME mag, 1986-02-17 p.52. Even though
171 # China is across 4 physical time zones, before Feb 1, 1986 only the
172 # Peking (Bejing) time zone was recognized. Since that date, China
173 # has two of 'em -- Peking's and Urumqi (named after the capital of
174 # the Xinjiang Uighur Autonomous Region). I don't know about DST for it.
175 #
176 # . . .I just deleted the DST table and this editor makes it too
177 # painful to suck in another copy.. So, here is what I have for
178 # DST start/end dates for Peking's time zone (info from AP):

185 # CHINA 9 H AHEAD OF UTC APR 17 - SEP 10
187 # From Paul Eggert <eggert@twinsun.com> (1995-12-19):
188 # Shanks writes that China has had a single time zone since 1980 May 1,
189 # observing summer DST from 1986 through 1991; this contradicts Devine's
190 # note about Time magazine, though apparently _something_ happened in 1986.

521 # According to the Office of the Secretary General of the Ministry of
522 # Interior, there is NO set rule for Daylight-Savings/Standard time changes.
523 # One thing is entrenched in law, however: that there must be at least 150
524 # days of daylight savings time annually. From 1993-1998, the change to
525 # daylight savings time was on a Friday morning from midnight IST to
526 # 1 a.m IDT; up until 1998, the change back to standard time was on a
527 # Saturday night from midnight daylight savings time to 11 p.m. standard
528 # time. 1996 is an exception to this rule where the change back to standard
529 # time took place on Sunday night instead of Saturday night to avoid
530 # conflicts with the Jewish New Year. Starting in 1999, the change to
531 # daylight savings time will still be on a Friday morning but from
532 # 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
533 # will now also be on a Friday morning from 2 a.m. IDT to 1 a.m. IST.

622 # This data is from 'Rika Nenpyou (Chronological Scientific Tables) 1996'
623 # edited by National Astronomical Observatory of Japan....
624 # JST (Japan Standard Time) has been used since 1888-01-01 00:00 (JST).
625 # The law is enacted on 1886-07-07.
627 # From Hideyuki Suzuki (1998-11-16):
628 # The ordinance No. 51 (1886) established "standard time" in Japan,
629 # which stands for the time on E 135 degree.
630 # In the ordinance No. 167 (1895), "standard time" was renamed to "central
631 # standard time". And the same ordinance also established "western standard
632 # time", which stands for the time on E 120 degree.... But "western standard
633 # time" was abolished in the ordinance No. 529 (1937). In the ordinance No.
634 # 167, there is no mention regarding for what place western standard time is
635 # standard....
636 #
637 # I wrote "ordinance" above, but I don't know how to translate.
638 # In Japanese it's "chokurei", which means ordinance from emperor.
640 # Shanks claims JST in use since 1896, and that a few places (e.g. Ishigaki)

868 # Palestine
870 # From Amos Shapir <amos@nsof.co.il> (1998-02-15):
871 #
872 # From 1917 until 1948-05-15, all of Palestine, including the parts now
873 # known as the Gaza Strip and the West Bank, was under British rule.
874 # Therefore the rules given for Israel for that period, apply there too...
875 #
876 # The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
877 # (except a short occupation by Israel from 1956-11 till 1957-03, but no
878 # time zone was affected then). It was never formally annexed to Egypt,
879 # though.
880 #
881 # The rest of Palestine was under Jordanian rule at that time, formally
882 # annexed in 1950 as the West Bank (and the word "Trans" was dropped from
883 # the country's previous name of "the Hashemite Kingdom of the
884 # Trans-Jordan"). So the rules for Jordan for that time apply. Major
885 # towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
886 # East Jerusalem.
887 #
888 # Both areas were occupied by Israel in June 1967, but not annexed (except
889 # for East Jerusalem). They were on Israel time since then; there might
890 # have been a Military Governor's order about time zones, but I'm not aware
891 # of any (such orders may have been issued semi-annually whenever summer
892 # time was in effect, but maybe the legal aspect of time was just neglected).
893 #
894 # The Palestinian Authority was established in 1993, and got hold of most
895 # towns in the West Bank and Gaza by 1995. I know that in order to
896 # demonstrate...independence, they have been switching to
897 # summer time and back on a different schedule than Israel's, but I don't
898 # know when this was started, or what algorithm is used (most likely the
899 # Jordanian one).
900 #
901 # To summarize, the table should probably look something like that:
902 #
903 # Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
904 # ------------+-----------+-----------+-----------+-----------
905 # Israel | Zion | Zion | Zion | Zion
906 # West bank | Zion | Jordan | Zion | Jordan
907 # Gaza | Zion | Egypt | Zion | Jordan
908 #
909 # I guess more info may be available from the PA's web page (if/when they
910 # have one).
912 # From Paul Eggert (1998-02-25):
913 # Shanks writes that Gaza did not observe DST until 1957, but we'll go
914 # with Shapir and assume that it observed DST from 1940 through 1947,
915 # and that it used Jordanian rules starting in 1996.
916 # We don't yet need a separate entry for the West Bank, since
917 # the only differences between it and Gaza that we know about
918 # occurred before our cutoff date of 1970.
919 # However, as we get more information, we may need to add entries
920 # for parts of the West Bank as they transitioned from Israel's rules
921 # to Palestine's rules. If you have more info about this, please
922 # send it to tz@elsie.nci.nih.gov for incorporation into future editions.
924 # From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time,
925 # forwarded by Ephraim Silverberg:
926 #
927 # Despite the fact that Israel changed over to daylight savings time
928 # last week, the PLO Authority (PA) has decided not to turn its clocks
929 # one-hour forward at this time. As a sign of independence from Israeli rule,
930 # the PA has decided to implement DST in April.
932 # These rules for Egypt are stolen from the `africa' file.
