bd7414aa 8# From Paul Eggert (2006-03-22):
984263bc
MD
9#
10# A good source for time zone historical data outside the U.S. is
bd7414aa
SW
11# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
12# San Diego: ACS Publications, Inc. (2003).
984263bc
MD
13#
14# Gwillim Law 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#
bd7414aa
SW
20# Except where otherwise noted, Shanks & Pottenger is the source for
21# entries through 1990, and IATA SSIM is the source for entries afterwards.
984263bc
MD
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# Previous editions of this database used WAT, CAT, SAT, and EAT
31# for +0:00 through +3:00, respectively,
9ffe4b14 32# but Mark R V Murray reports that
984263bc
MD
33# `SAST' is the official abbreviation for +2:00 in the country of South Africa,
34# `CAT' is commonly used for +2:00 in countries north of South Africa, and
35# `WAT' is probably the best name for +1:00, as the common phrase for
36# the area that includes Nigeria is ``West Africa''.
37# He has heard of ``Western Sahara Time'' for +0:00 but can find no reference.
38#
39# To make things confusing, `WAT' seems to have been used for -1:00 long ago;
40# I'd guess that this was because people needed _some_ name for -1:00,
41# and at the time, far west Africa was the only major land area in -1:00.
42# This usage is now obsolete, as the last use of -1:00 on the African
43# mainland seems to have been 1976 in Western Sahara.
44#
45# To summarize, the following abbreviations seem to have some currency:
46# -1:00 WAT West Africa Time (no longer used)
47# 0:00 GMT Greenwich Mean Time
48# 2:00 CAT Central Africa Time
49# 2:00 SAST South Africa Standard Time
50# and Murray suggests the following abbreviation:
51# 1:00 WAT West Africa Time
52# I realize that this leads to `WAT' being used for both -1:00 and 1:00
53# for times before 1976, but this is the best I can think of
54# until we get more information.
55#
56# I invented the following abbreviations; corrections are welcome!
57# 2:00 WAST West Africa Summer Time
58# 2:30 BEAT British East Africa Time (no longer used)
59# 2:44:45 BEAUT British East Africa Unified Time (no longer used)
60# 3:00 CAST Central Africa Summer Time (no longer used)
61# 3:00 SAST South Africa Summer Time (no longer used)
62# 3:00 EAT East Africa Time

420# From Petronella Sibeene (2007-03-30) in
421# <http://allafrica.com/stories/200703300178.html>:
422# While the entire country changes its time, Katima Mulilo and other
423# settlements in Caprivi unofficially will not because the sun there
424# rises and sets earlier compared to other regions. Chief of
425# Forecasting Riaan van Zyl explained that the far eastern parts of
426# the country are close to 40 minutes earlier in sunrise than the rest
427# of the country.
428#
429# From Paul Eggert (2007-03-31):
430# Apparently the Caprivi Strip informally observes Botswana time, but
431# we have no details. In the meantime people there can use Africa/Gaborone.
