7 # From Paul Eggert <eggert@twinsun.com> (1995-07-24):
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 # Another source occasionally used is Edward W. Whitman, World Time Differences,
15 # Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
16 # I found in the UCLA library.
17 #
18 # A reliable and entertaining source about time zones is
19 # Derek Howse, Greenwich time and the discovery of the longitude,
20 # Oxford University Press (1980).
21 #
22 # I invented the abbreviations marked `*' in the following table;
23 # the rest are from earlier versions of this file, or from other sources.
24 # Corrections are welcome!

142 # People's Republic of China
144 # From Guy Harris:
145 # People's Republic of China. Yes, they really have only one time zone.
147 # From Bob Devine (1988-01-28):
148 # No they don't. See TIME mag, 1986-02-17 p.52. Even though
149 # China is across 4 physical time zones, before Feb 1, 1986 only the
150 # Peking (Bejing) time zone was recognized. Since that date, China
151 # has two of 'em -- Peking's and Urumqi (named after the capital of
152 # the Xinjiang Uighur Autonomous Region). I don't know about DST for it.
153 #
154 # . . .I just deleted the DST table and this editor makes it too
155 # painful to suck in another copy.. So, here is what I have for
156 # DST start/end dates for Peking's time zone (info from AP):
157 #
158 # 1986 May 4 - Sept 14
159 # 1987 mid-April - ??
161 # From U. S. Naval Observatory (1989-01-19):
162 # CHINA 8 H AHEAD OF UTC ALL OF CHINA, INCL TAIWAN
163 # CHINA 9 H AHEAD OF UTC APR 17 - SEP 10
165 # From Paul Eggert <eggert@twinsun.com> (1995-12-19):
166 # Shanks writes that China has had a single time zone since 1980 May 1,
167 # observing summer DST from 1986 through 1991; this contradicts Devine's
168 # note about Time magazine, though apparently _something_ happened in 1986.
169 # Go with Shanks for now. I made up names for the other pre-1980 time zones.

421 # From Ephraim Silverberg (1996-01-02):
422 #
423 # According to the Office of the Secretary General of the Ministry of
424 # Interior, there is NO set rule for Daylight-Savings/Standard time changes.
425 # Each year they decide anew what havoc to wreak on the country. However,
426 # there is a "supposed" set of rules which is subject to change depending
427 # on the party the Minister of Interior, the size of the coalition
428 # government, the phase of the moon and the direction of the wind. Hence,
429 # changes may need to be made on a semi-annual basis. One thing is entrenched
430 # in law, however: that there must be at least 150 days of daylight savings
431 # time annually. Ever since 1993, the change to daylight savings time has
432 # been from midnight Thursday night to 1 a.m. Friday morning and the change
433 # back to standard time on Saturday night from midnight daylight savings time
434 # to 11 p.m. standard time. 1996 is an exception to this rule where the
435 # change back to standard time takes place on Sunday night instead of Saturday
436 # night to avoid conflicts with the Jewish New Year.

466 # Emptor Caveat: The dates for the years 1996-1998 were originally announced
467 # on 1995-08-31, by the previous Minister of Interior. The new Minister
468 # of Interior changed the dates on 1996-01-01, to take into account the
469 # desires of certain portions of Israeli society (the next election is in the
470 # Fall of 1996). After this (1996) year's Daylight Savings Time is over, the
471 # new minister has announced that a study will be conducted as to the wishes of
472 # the populace regarding the length of Daylight Savings Time and the Interior
473 # Committee will meet to review the results of the study and make any necessary
474 # changes to the 1997-1998 dates. Never a dull moment in the State of Israel.
