18# Many years ago Gwillim Law wrote that a good source
19# for time zone data was the International Air Transport
984263bc
MD
20# Association's Standard Schedules Information Manual (IATA SSIM),
21# published semiannually. Law sent in several helpful summaries
03b0b587

22# of the IATA's data after 1990. Except where otherwise noted,
23# IATA SSIM is the source for entries after 1990.

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.

33# European-style abbreviations are commonly used along the Mediterranean.
34# For sub-Saharan Africa abbreviations were less standardized.
984263bc 35# Previous editions of this database used WAT, CAT, SAT, and EAT
83b0991f
SW
36# for UT +00 through +03, respectively,
37# but in 1997 Mark R V Murray reported that
38# 'SAST' is the official abbreviation for +02 in the country of South Africa,
39# 'CAT' is commonly used for +02 in countries north of South Africa, and
40# 'WAT' is probably the best name for +01, as the common phrase for
48afb8ac 41# the area that includes Nigeria is "West Africa".
984263bc 42#

43# To summarize, the following abbreviations seemed to have some currency:
44# +00 GMT Greenwich Mean Time
45# +02 CAT Central Africa Time
46# +02 SAST South Africa Standard Time
47# and Murray suggested the following abbreviation:
48# +01 WAT West Africa Time
49# Murray's suggestion seems to have caught on in news reports and the like.
50# I vaguely recall 'WAT' also being used for -01 in the past but
51# cannot now come up with solid citations.
984263bc 52#

53# I invented the following abbreviations in the 1990s:
54# +02 WAST West Africa Summer Time
55# +03 CAST Central Africa Summer Time
56# +03 SAST South Africa Summer Time
83b0991f 57# +03 EAT East Africa Time
8cb73418
SW
58# 'EAT' seems to have caught on and is in current timestamps, and though
59# the other abbreviations are rarer and are only in past timestamps,
60# they are paired with better-attested non-DST abbreviations.

227# than the year of the Gregorian calendar, Ramadan shifts earlier each
228# year. This year it will be observed September 13 (September is quite
229# hot in Egypt), and the idea is to make fasting easier for workers by
230# shifting business hours one hour out of daytime heat. Consequently,
231# unless discontinued, next DST may end Thursday 28 August 2008.

885# In Morocco (where I live), the end of Ramadan (Arabic month) is followed by
886# the Eid al-Fitr, and concretely it's 1 or 2 day offs for the people (with
887# traditional visiting of family, big lunches/dinners, etc.). So for this
888# year the astronomical calculations don't include the following 2 days off in
889# the calc. These 2 days fall in a Sunday/Monday, so it's not acceptable by
890# people to have a time shift during these 2 days off. Perhaps you can modify
891# the (predicted) rules for next years: if the end of Ramadan is a (probable)
892# Friday or Saturday (and so the 2 days off are on a weekend), the next time

1263# Lloyd's Register of Shipping (1915) says "Hitherto the time observed in Lagos
1264# was the local mean time. On 1st January, 1914, standard time for the whole of
1265# Nigeria was introduced ... Lagos time has been advanced about 16 minutes

1281# "The proposal is that the Globe should be divided into twelve zones East and
1282# West of Greenwich, of one hour each, Nigeria falling into the zone with a
