30# From Paul Eggert (2006-03-22):
31#
32# A good source for time zone historical data outside the U.S. is
33# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
34# San Diego: ACS Publications, Inc. (2003).
35#
36# Gwillim Law writes that a good source
37# for recent time zone data is the International Air Transport
38# Association's Standard Schedules Information Manual (IATA SSIM),
39# published semiannually. Law sent in several helpful summaries
40# of the IATA's data after 1990.
41#
42# Except where otherwise noted, Shanks & Pottenger is the source for
43# entries through 1990, and IATA SSIM is the source for entries afterwards.
44#
45# Another source occasionally used is Edward W. Whitman, World Time Differences,
46# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
47# I found in the UCLA library.
48#
49# A reliable and entertaining source about time zones is
50# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
51#
52# Previous editions of this database used WAT, CAT, SAT, and EAT
53# for +0:00 through +3:00, respectively,
54# but Mark R V Murray reports that
55# `SAST' is the official abbreviation for +2:00 in the country of South Africa,
56# `CAT' is commonly used for +2:00 in countries north of South Africa, and
57# `WAT' is probably the best name for +1:00, as the common phrase for
58# the area that includes Nigeria is ``West Africa''.
59# He has heard of ``Western Sahara Time'' for +0:00 but can find no reference.
60#
61# To make things confusing, `WAT' seems to have been used for -1:00 long ago;
62# I'd guess that this was because people needed _some_ name for -1:00,
63# and at the time, far west Africa was the only major land area in -1:00.
64# This usage is now obsolete, as the last use of -1:00 on the African
65# mainland seems to have been 1976 in Western Sahara.
66#
67# To summarize, the following abbreviations seem to have some currency:
68# -1:00 WAT West Africa Time (no longer used)
69# 0:00 GMT Greenwich Mean Time
70# 2:00 CAT Central Africa Time
71# 2:00 SAST South Africa Standard Time
72# and Murray suggests the following abbreviation:
73# 1:00 WAT West Africa Time
74# I realize that this leads to `WAT' being used for both -1:00 and 1:00
75# for times before 1976, but this is the best I can think of
76# until we get more information.
77#
78# I invented the following abbreviations; corrections are welcome!
79# 2:00 WAST West Africa Summer Time
80# 2:30 BEAT British East Africa Time (no longer used)
81# 2:44:45 BEAUT British East Africa Unified Time (no longer used)
82# 3:00 CAST Central Africa Summer Time (no longer used)
83# 3:00 SAST South Africa Summer Time (no longer used)
84# 3:00 EAT East Africa Time
85# 4:00 EAST East Africa Summer Time (no longer used)

255# year. This year it will be observed September 13 (September is quite
256# hot in Egypt), and the idea is to make fasting easier for workers by
257# shifting business hours one hour out of daytime heat. Consequently,
258# unless discontinued, next DST may end Thursday 28 August 2008.

462# While the entire country changes its time, Katima Mulilo and other
463# settlements in Caprivi unofficially will not because the sun there
464# rises and sets earlier compared to other regions. Chief of

467# of the country.

470# Apparently the Caprivi Strip informally observes Botswana time, but
