Shanks, The International Atlas (5th edition), 12# San Diego: ACS Publications, Inc. (1999). 13# 14# Gwillim Law <Gwil_Law@bridge-point.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, Philip Wilson Publishers (1997). 29# 30# I invented the abbreviations marked `*' in the following table; 31# the rest are from earlier versions of this file, or from other sources. 32# Corrections are welcome! 33# std dst 34# LMT Local Mean Time 35# 2:00 EET EEST Eastern European Time 36# 2:00 IST IDT Israel 37# 3:00 AST ADT Arabia* 38# 4:00 GST Gulf* 39# 5:30 IST India 40# 7:00 ICT Indochina* 41# 8:00 CST China 42# 9:00 CJT Central Japanese Time (1896/1937)* 43# 9:00 JST Japan 44# 9:00 KST Korea 45# 9:30 CST (Australian) Central Standard Time 46# 47# See the `europe' file for Russia and Turkey in Asia. 48 49# From Guy Harris: 50# Incorporates data for Singapore from Robert Elz' asia 1.1, as well as 51# additional information from Tom Yap, Sun Microsystems Intercontinental 52# Technical Support (including a page from the Official Airline Guide - 53# Worldwide Edition).

Major 961# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and 962# East Jerusalem. 963# 964# Both areas were occupied by Israel in June 1967, but not annexed (except 965# for East Jerusalem). They were on Israel time since then; there might 966# have been a Military Governor's order about time zones, but I'm not aware 967# of any (such orders may have been issued semi-annually whenever summer 968# time was in effect, but maybe the legal aspect of time was just neglected). 969# 970# The Palestinian Authority was established in 1993, and got hold of most 971# towns in the West Bank and Gaza by 1995. I know that in order to 972# demonstrate...independence, they have been switching to 973# summer time and back on a different schedule than Israel's, but I don't 974# know when this was started, or what algorithm is used (most likely the 975# Jordanian one). 976# 977# To summarize, the table should probably look something like that: 978# 979# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996- 980# ------------+-----------+-----------+-----------+----------- 981# Israel | Zion | Zion | Zion | Zion 982# West bank | Zion | Jordan | Zion | Jordan 983# Gaza | Zion | Egypt | Zion | Jordan 984# 985# I guess more info may be available from the PA's web page (if/when they 986# have one). 987 988# From Paul Eggert (1998-02-25): 989# Shanks writes that Gaza did not observe DST until 1957, but we'll go 990# with Shapir and assume that it observed DST from 1940 through 1947, 991# and that it used Jordanian rules starting in 1996. 992# We don't yet need a separate entry for the West Bank, since 993# the only differences between it and Gaza that we know about 994# occurred before our cutoff date of 1970. 995# However, as we get more information, we may need to add entries 996# for parts of the West Bank as they transitioned from Israel's rules 997# to Palestine's rules. If you have more info about this, please 998# send it to tz@elsie.nci.nih.gov for incorporation into future editions. 999 1000# From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time, 1001# forwarded by Ephraim Silverberg: 1002# 1003# Despite the fact that Israel changed over to daylight savings time 1004# last week, the PLO Authority (PA) has decided not to turn its clocks 1005# one-hour forward at this time. As a sign of independence from Israeli rule, 1006# the PA has decided to implement DST in April. 1007 1008# From Paul Eggert (1999-09-20): 1009# Daoud Kuttab writes in 1010# <a href="http://www.jpost.com/com/Archive/22.Apr.1999/Opinion/Article-2.html"> 1011# Holiday havoc 1012# </a> (Jerusalem Post, 1999-04-22) that 1013# the Palestinian National Authority changed to DST on 1999-04-15. 1014# I vaguely recall that they switch back in October (sorry, forgot the source). 1015# For now, let's assume that the spring switch was at 24:00, 1016# and that they switch at 0:00 on the 3rd Fridays of April and October. 1017 1018# The rules for Egypt are stolen from the `africa' file. 1019# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S 1020Rule EgyptAsia 1957 only -
