+# From Guy Harris:
+# People's Republic of China.  Yes, they really have only one time zone.
+
+# From Bob Devine (January 28, 1988):
+# No they don't.  See TIME mag, February 17, 1986 p.52.  Even though
+# China is across 4 physical time zones, before Feb 1, 1986 only the
+# Peking (Bejing) time zone was recognized.  Since that date, China
+# has two of 'em -- Peking's and Urumqi (named after the capital of
+# the Xinjiang Uighur Autonomous Region).  I don't know about DST for it.
+#
+# . . .I just deleted the DST table and this editor makes it too
+# painful to suck in another copy..  So, here is what I have for

+# ISRAEL              3 H  AHEAD OF UTC  APR 10 - SEP 3
+
+# From Ephraim Silverberg (April 18, 1989):
+
+# Prior to 1989, the rules concerning Daylight Savings Time changed every
+# year; as information, regarding exact times and dates during this period,
+# is not readily available at the present time, the rules commence starting
+# with the year 1989.
+
+# From 1989 onwards the rules are as follows:
+#
+# 1. Daylight Savings Time commences midnight of the first Saturday night
+#    following the seven-day festival of Pesach (Passover).  The transition
+#    is from midnight Israel Standard Time to 1 a.m. Israel Daylight Savings
+#    time.  As the Pesach festival is dependent on the Lunar calendar (the
+#    first day is always on the 15th day of the month of Nisan), the rule
+#    changes every year on the Gregorian calendar.
+#
+# 2. Standard Time is reinstated on the Saturday night whereupon Jews
+#    following the Ashkenazi (European) rite begin to recite the Selichot
+#    (forgiveness) prayers prior to the Jewish Lunar New Year.  The transition
+#    is from midnight Israel Daylight Savings time to 11 p.m. Israel Standard
+#    Time.  The law (according to the Ashkenazi custom) concerning the
+#    commencement of the Selichot prayers is described in chapter 128, section
+#    5 of the "Code of Jewish Law," by Rabbi Shlomo Ganzfried (translated by
+#    Hyman E. Goldin):
+#
+#       Beginning with the Sunday [**] before Rosh Hashanah [***],
+#       we rise early for the service of Selichot (supplications for
+#       forgiveness).  If Rosh Hashanah occurs on Monday or Tuesday, we
+#       begin saying the Selichot from the Sunday of the preceding week.
+#
+#    This, too, varies from year to year on the Gregorian calendar and, thus,
+#    two explicit timezone rules are required for each Gregorian year.
+#
+#    [**] actually Saturday night as the Jewish day commences at nightfall.
+#    [***] the Jewish Lunar New Year.

+# ...the European time rules are...standardized since 1981, when
+# most European coun[tr]ies started DST.  Before that year, only
+# a few countries (UK, France, Italy) had DST, each according
+# to own national rules.  In 1981, however, DST started on
+# 'Apr firstSun', and not on 'Mar lastSun' as in the following
+# years...
+# But also since 1981 there are some more national exceptions 
+# than listed in 'europe': Switzerland, for example, joined DST 
+# one year later, Denmark ended DST on 'Oct 1' instead of 'Sep 
+# lastSun' in 1981---I don't know how they handle now.
+# 
+# Finally, DST ist always from 'Apr 1' to 'Oct 1' in the
+# Soviet Union (as far as I know).

+# The information from Tom Hofmann is (as far as I know) not entirely correct.
+# After a request from chongo at amdahl I tried to retrieve all information
+# about DST in Europe.  I was able to find all from about 1969.
+# 
+# ...standardization on DST in Europe started in about 1977 with switches on
+# first Sunday in April and last Sunday in September...
+# In 1981 UK joined Europe insofar that
+# the starting day for both shifted to last Sunday in March.  And from 1982
+# the whole of Europe used DST, with switch dates April 1 and October 1 in
+# the Sov[i]et Union.  In 1985 the SU reverted to standard Europe[a]n switch
+# dates...
+# 
+# It should also be remembered that time-zones are not constants; e.g.
+# Portugal switched in 1976 from MET (or CET) to WET with DST...
+# Note also that though there were rules for switch dates not
+# all countries abided to these dates, and many individual deviations
+# occurred, though not since 1982 I believe.  Another note: it is always
+# assumed that DST is 1 hour ahead of normal time, this need not be the
+# case; at least in the Netherlands there have been times when DST was 2 hours
+# in advance of normal time.
