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

+# From Daniel C. Sobral <dcs@gns.com.br> (1998-02-12):

+# they bought the wrong times on satellite for coverage of Pope's visit.
+# This year, the ending date of DS was postponed to March 1
