7 # From Paul Eggert <eggert@twinsun.com> (August 18, 1994):
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.

145 # From Guy Harris:
146 # People's Republic of China. Yes, they really have only one time zone.
148 # From Bob Devine (January 28, 1988):
149 # No they don't. See TIME mag, February 17, 1986 p.52. Even though
150 # China is across 4 physical time zones, before Feb 1, 1986 only the
151 # Peking (Bejing) time zone was recognized. Since that date, China
152 # has two of 'em -- Peking's and Urumqi (named after the capital of
153 # the Xinjiang Uighur Autonomous Region). I don't know about DST for it.
154 #
155 # . . .I just deleted the DST table and this editor makes it too
156 # painful to suck in another copy.. So, here is what I have for
157 # DST start/end dates for Peking's time zone (info from AP):
158 #
159 # 1986 May 4 - Sept 14
160 # 1987 mid-April - ??
162 # From Paul Eggert <eggert@twinsun.com> (November 18, 1993):
163 # According to Shanks, China started using DST in 1986,
164 # but it's still all one big happy time zone.
166 # From U. S. Naval Observatory (January 19, 1989):
167 # CHINA 8 H AHEAD OF UTC ALL OF CHINA, INCL TAIWAN
168 # CHINA 9 H AHEAD OF UTC APR 17 - SEP 10
170 # From Paul Eggert <eggert@twinsun.com> (November 18, 1993):
171 # Shanks writes that China switched from the Chinese calendar on 1912 Feb 12.
172 # He also writes that China has had a single time zone since 1980 May 1,
173 # and that they instituted DST on 1986 May 4; this contradicts Devine's
174 # note about Time magazine, though apparently _something_ happened in 1986.

433 # According to the Office of the Secretary General of the Ministry of
434 # Interior, there is NO set rule for Daylight-Savings/Standard time changes.
435 # Each year they decide anew what havoc to wreak on the country. However,
436 # there is a "supposed" set of rules which is subject to change depending
437 # on the party the Minister of Interior, the size of the coalition
438 # government, the phase of the moon and the direction of the wind. Hence,
439 # changes may need to be made on a semi-annual basis. One thing is entrenched
440 # in law, however: that there must be at least 150 days on daylight savings
441 # time annually.

486 # Today's _Asahi Evening News_ (page 4) reports that Japan had
487 # daylight saving between 1948 and 1951, but ``the system was discontinued
488 # because the public believed it would lead to longer working hours.''
