10
# From Paul Eggert (2006-03-22):
12
# A good source for time zone historical data outside the U.S. is
13
# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
14
# San Diego: ACS Publications, Inc. (2003).
16
# Gwillim Law writes that a good source
17
# for recent time zone data is the International Air Transport
18
# Association's Standard Schedules Information Manual (IATA SSIM),
19
# published semiannually. Law sent in several helpful summaries
20
# of the IATA's data after 1990.
22
# Except where otherwise noted, Shanks & Pottenger is the source for
23
# entries through 1990, and IATA SSIM is the source for entries afterwards.
25
# Another source occasionally used is Edward W. Whitman, World Time Differences,
26
# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
27
# I found in the UCLA library.
29
# A reliable and entertaining source about time zones is
30
# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
32
# Previous editions of this database used WAT, CAT, SAT, and EAT
33
# for +0:00 through +3:00, respectively,
34
# but Mark R V Murray reports that
35
# `SAST' is the official abbreviation for +2:00 in the country of South Africa,
36
# `CAT' is commonly used for +2:00 in countries north of South Africa, and
37
# `WAT' is probably the best name for +1:00, as the common phrase for
38
# the area that includes Nigeria is ``West Africa''.
39
# He has heard of ``Western Sahara Time'' for +0:00 but can find no reference.
41
# To make things confusing, `WAT' seems to have been used for -1:00 long ago;
42
# I'd guess that this was because people needed _some_ name for -1:00,
43
# and at the time, far west Africa was the only major land area in -1:00.
44
# This usage is now obsolete, as the last use of -1:00 on the African
45
# mainland seems to have been 1976 in Western Sahara.
47
# To summarize, the following abbreviations seem to have some currency:
48
# -1:00 WAT West Africa Time (no longer used)
49
# 0:00 GMT Greenwich Mean Time
50
# 2:00 CAT Central Africa Time
51
# 2:00 SAST South Africa Standard Time
52
# and Murray suggests the following abbreviation:
53
# 1:00 WAT West Africa Time
54
# I realize that this leads to `WAT' being used for both -1:00 and 1:00
55
# for times before 1976, but this is the best I can think of
56
# until we get more information.
58
# I invented the following abbreviations; corrections are welcome!
59
# 2:00 WAST West Africa Summer Time
60
# 2:30 BEAT British East Africa Time (no longer used)
61
# 2:44:45 BEAUT British East Africa Unified Time (no longer used)
62
# 3:00 CAST Central Africa Summer Time (no longer used)
63
# 3:00 SAST South Africa Summer Time (no longer used)
64

# From Abdelrahman Hassan (2007-09-06):
233
# Due to the Hijri (lunar Islamic calendar) year being 11 days shorter
234
# than the year of the Gregorian calendar, Ramadan shifts earlier each
235
# year. This year it will be observed September 13 (September is quite
236
# hot in Egypt), and the idea is to make fasting easier for workers by
237
# shifting business hours one hour out of daytime heat. Consequently,
238
# unless discontinued, next DST may end Thursday 28 August 2008.

# Mauritius plans to observe DST from 2008-11-01 to 2009-03-31 on a trial

# The www.timeanddate.com article cited by Steffen Thorsen notes that "A

464
# would begin and end on these dates." As a place holder, use midnight.

474
# (in French), Mauritius will start and end their DST a few days earlier
475
# than previously announced (2008-11-01 to 2009-03-31). The new start
476
# date is 2008-10-26 at 02:00 and the new end date is 2009-03-27 (no time
477
# given, but it is probably at either 2 or 3 wall clock time).
479
# A little strange though, since the article says that they moved the date
480
# to align itself with Europe and USA which also change time on that date,
481
# but that means they have not paid attention to what happened in
482
# USA/Canada last year (DST ends first Sunday in November). I also wonder
483
# why that they end on a Friday, instead of aligning with Europe which
484
# changes two days later.

# From Gwillim Law (2005-04-30):

# My correspondent, Risto Nykanen, has alerted me to another adoption of DST,
889
# this time in Tunisia. According to Yahoo France News
890
# <http://fr.news.yahoo.com/050426/5/4dumk.html>, in a story attributed to AP
891
# and dated 2005-04-26, "Tunisia has decided to advance its official time by
892
# one hour, starting on Sunday, May 1. Henceforth, Tunisian time will be
893
# UTC+2 instead of UTC+1. The change will take place at 23:00 UTC next
894
# Saturday." (My translation)

# From Arthur David Olson (2009--3-18):
940
# The Tunis Afrique Presse News Agency notice contains this: "This measure is due to the fact
941
# that the fasting month of ramadan coincides with the period concerned by summer time.
942
# Therefore, the standard time will be kept unchanged the whole year long."
943
# So foregoing DST seems to be an exception (albeit one that may be repeated in the future).
