7# From Paul Eggert <eggert@twinsun.com> (1999-03-22):
8#
9# A good source for time zone historical data outside the U.S. is
10# Thomas G. Shanks, The International Atlas (5th edition),
11# San Diego: ACS Publications, Inc. (1999).
12#
13# Gwillim Law writes that a good source
14# for recent time zone data is the International Air Transport
15# Association's Standard Schedules Information Manual (IATA SSIM),
16# published semiannually.  Law sent in several helpful summaries
17# of the IATA's data after 1990.
18#
19# Except where otherwise noted, Shanks is the source for entries through 1990,
20# and IATA SSIM is the source for entries after 1990.
21#
22# Another source occasionally used is Edward W. Whitman, World Time Differences,
23# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
24# I found in the UCLA library.
25#
26# A reliable and entertaining source about time zones is
27# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
28#
29# Previous editions of this database used WAT, CAT, SAT, and EAT
30# for +0:00 through +3:00, respectively,
31# but Mark R V Murray <markm@grondar.za> reports that
32# `SAST' is the official abbreviation for +2:00 in the country of South Africa,
33# `CAT' is commonly used for +2:00 in countries north of South Africa, and
34# `WAT' is probably the best name for +1:00, as the common phrase for
35# the area that includes Nigeria is ``West Africa''.
36# He has heard of ``Western Sahara Time'' for +0:00 but can find no reference.
37#
38# To make things confusing, `WAT' seems to have been used for -1:00 long ago;
39# I'd guess that this was because people needed _some_ name for -1:00,
40# and at the time, far west Africa was the only major land area in -1:00.
41# This usage is now obsolete, as the last use of -1:00 on the African
42# mainland seems to have been 1976 in Western Sahara.
43#
44# To summarize, the following abbreviations seem to have some currency:
45#	-1:00	WAT	West Africa Time (no longer used)
46#	 0:00	GMT	Greenwich Mean Time
47#	 2:00	CAT	Central Africa Time
48#	 2:00	SAST	South Africa Standard Time
49# and Murray suggests the following abbreviation:
50#	 1:00	WAT	West Africa Time
51# I realize that this leads to `WAT' being used for both -1:00 and 1:00
52# for times before 1976, but this is the best I can think of
53# until we get more information.
54#
55# I invented the following abbreviations; corrections are welcome!
56#	 2:00	WAST	West Africa Summer Time
57#	 2:30	BEAT	British East Africa Time (no longer used)
58#	 2:44:45 BEAUT	British East Africa Unified Time (no longer used)
59#	 3:00	CAST	Central Africa Summer Time (no longer used)
60#	 3:00	SAST	South Africa Summer Time (no longer used)
61#	 3:00	EAT	East Africa Time
62#	 4:00	EAST	East Africa Summer Time (no longer used)
