Shanks, The International Atlas (3rd edition), +# San Diego: ACS Publications, Inc. (1991). +# Except where otherwise noted, it is the source for the data below. +# +# Another source occasionally used is Edward W. Whitman, World Time Differences, +# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which +# I found in the UCLA library. +# +# I added so many Zone names that the old, mostly flat name space was unwieldy. +# So I renamed the Zones to have the form AREA/LOCATION, where +# AREA is the name of a continent or ocean, and +# LOCATION is the name of a specific location within that region. +# For example, the old zone name `Egypt' is now `Africa/Cairo'. +# +# Here are the general rules I used for choosing location names, +# in decreasing order of importance: +# +# Use only valid Posix file names. Use only Ascii letters, digits, `.', +# `-' and `_'. Do not exceed 14 characters or start with `-'. +# E.g. prefer `Brunei' to `Bandar_Seri_Begawan'. +# Include at least one location per time zone rule set per country. +# One such location is enough. +# If a name is ambiguous, use a less ambiguous alternative; +# e.g. many cities are named San Jose and Georgetown, so +# prefer `Costa_Rica' to `San_Jose' and `Guyana' to `Georgetown'. +# Keep locations compact. Use cities or small islands, not countries +# or regions, so that any future time zone changes do not split +# locations into different time zones. E.g. prefer `Paris' +# to `France', since France has had multiple time zones. +# Use traditional English spelling, e.g. prefer `Rome' to `Roma', and +# prefer `Athens' to the true name (which uses Greek letters). +# The Posix file name restrictions encourage this rule. +# Use the most populous among locations in a country's time zone, +# e.g. prefer `Shanghai' to `Beijing'. Among locations with +# similar populations, pick the best-known location, +# e.g. prefer `Rome' to `Milan'. +# Use the singular form, e.g. prefer `Canary' to `Canaries'. +# Omit common suffixes like `_Islands' and `_City', unless that +# would lead to ambiguity. E.g. prefer `Cayman' to +# `Cayman_Islands' and `Guatemala' to `Guatemala_City', +# but prefer `Mexico_City' to `Mexico' because the country +# of Mexico has several time zones. +# Use `_' to represent a space. +# Omit `.' from abbreviations in names, e.g. prefer `St_Helena' +# to `St._Helena'. +# +# We typically use traditional English time zone abbreviations, +# and assume that applications translate them to other languages +# as part of the normal localization process. +# +# I made up the following time zone abbreviations; corrections are welcome! +# LMT Local Mean Time +# -2:00 CVT Cape Verde Time (no longer used) +# -1:00 AAT Atlantic Africa Time +# 0:00 WAT West Africa Time +# 1:00 CAT Central Africa Time +# 2:00 SAT South Africa Time +# 3:00 EAT East Africa Time +# 4:00 SMT Seychelles and Mascarene Time +# The final `T' is replaced by `ST' for summer time, e.g. `SAST'. +# BEAT is British East Africa Time, which was 2:30 before 1948 and 2:45 after. + + +# Algeria +# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S +Rule Algeria 1911 only - Jan 1 0:00s 0 - +Rule Algeria 1916 only - Jun 14 23:00s 1:00 " DST" +Rule Algeria 1916 1919 - Oct Sun<=7 23:00s 0 - +Rule Algeria 1917 only - Mar 24 23:00s 1:00 " DST" +Rule Algeria 1918 only - Mar 9 23:00s 1:00 " DST" +Rule Algeria 1919 only - Mar 1 23:00s 1:00 " DST" +Rule Algeria 1920 only - Feb 14 23:00s 1:00 " DST" +Rule Algeria 1920 only - Oct 23 23:00s 0 - +Rule Algeria 1921 only - Mar 14 23:00s 1:00 " DST" +Rule Algeria 1921 only - Jun 21 23:00s 0 - +Rule Algeria 1939 only - Sep 11 23:00s 1:00 " DST" +Rule Algeria 1939 only - Nov 19 1:00 0 - +Rule Algeria 1944 1945 - Apr Mon<=7 2:00 1:00 " DST" +Rule Algeria 1944 only - Oct 8 2:00 0 - +Rule Algeria 1945 only - Sep 16 1:00 0 - +Rule Algeria 1971 only - Apr 25 23:00s 1:00 " DST" +Rule Algeria 1971 only - Sep 26 23:00s 0 - +Rule Algeria 1977 only - May 6 0:00 1:00 " DST" +Rule Algeria 1977 only - Oct 21 0:00 0 - +Rule Algeria 1978 only - Mar 24 1:00 1:00 " DST" +Rule Algeria 1978 only - Sep 22 3:00 0 - +Rule Algeria 1980 only - Apr 25 0:00 1:00 " DST" +Rule Algeria 1980 only - Oct 31 2:00 0 - +# Shanks gives 0:09 for Paris Mean Time; go with Whitman's more precise 0:09:05. +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Africa/Algiers 0:12:12 - LMT 1891 Mar 15 0:01 + 0:09:05 - PMT 1911 Mar 11 # Paris Mean Time + 0:00 Algeria WET%s 1940 Feb 25 2:00 + 1:00 Algeria MET%s 1946 Oct 7 + 0:00 - WET 1956 Jan 29 + 1:00 - MET 1963 Apr 14 + 0:00 Algeria WET%s 1977 Oct 21 + 1:00 Algeria MET%s 1979 Oct 26 + 0:00 Algeria WET%s 1981 May + 1:00 - MET + +# Angola +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Africa/Luanda 0:52:56 - LMT 1892 + 0:52 - LMT 1911 May 26 # Luanda Mean Time + 1:00 - CAT + +# Benin +# Whitman says they switched to 1:00 in 1946, not 1934; go with Shanks. +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Africa/Porto-Novo 0:10:28 - LMT 1912 + 0:00 - WAT 1934 Feb 26 + 1:00 - CAT + +# Botswana +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Africa/Gaborone 1:43:40 - LMT 1885 + 2:00 - SAT 1943 Sep 19 2:00 + 2:00 1:00 SAST 1944 Mar 19 2:00 + 2:00 - SAT + +# Burkina Faso +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Africa/Ouagadougou -0:06:04 - LMT 1912 + 0:00 - WAT + +# Burundi +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Africa/Bujumbura 1:57:28 - LMT 1890 + 2:00 - SAT + +# Cameroon +# Whitman says they switched to 1:00 in 1920; go with Shanks. +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Africa/Douala 0:38:48 - LMT 1912 + 1:00 - CAT + +# Cape Verde +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Atlantic/Cape_Verde -1:34:04 - LMT 1907 # Praia + -2:00 - CVT 1942 Sep + -2:00 1:00 CVST 1945 Oct 15 + -2:00 - CVT 1975 Nov 25 2:00 + -1:00 - AAT + +# Central African Republic +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Africa/Bangui 1:14:20 - LMT 1912 + 1:00 - CAT + +# Chad +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Africa/Ndjamena 1:00:12 - LMT 1912 + 1:00 - CAT 1979 Oct 14 + 1:00 1:00 CAST 1980 Mar 8 + 1:00 - CAT + +# Comoros +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Indian/Comoro 2:53:04 - LMT 1911 Jul # Moroni, Gran Comoro + 3:00 - EAT + +# Congo +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Africa/Brazzaville 1:01:08 - LMT 1912 + 1:00 - CAT + +# Cote D'Ivoire +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Africa/Abidjan -0:16:08 - LMT 1912 + 0:00 - WAT + +# Djibouti +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Africa/Djibouti 2:52:36 - LMT 1911 Jul + 3:00 - EAT + +############################################################################### + +# Egypt + +# From Bob Devine (January 28, 1988): +# Egypt: DST from first day of May to first of October (ending may +# also be on Sept 30th not 31st -- you might want to ask one of the +# soc.* groups, you might hit someone who could ask an embassy). +# DST since 1960 except for 1981-82. + +# From U.

Now by a happy coincidence, `summer' +# and `standard' happen to start with the same letter; hence, the +# abbreviation does _not_ change... +# The legislation does not actually define abbreviations, at least +# in this State, but the abbreviation is just commonly taken to be the +# initials of the phrase, and the legislation here uniformly uses +# the phrase `summer time' and does not use the phrase `daylight +# time'. +# Announcers on the Commonwealth radio network, the ABC (for Australian +# Broadcasting Commission), use the phrases `Eastern Standard Time' +# or `Eastern Summer Time'. (Note, though, that as I say in the +# current australasia file, there is really no such thing.) Announcers +# on its overseas service, Radio Australia, use the same phrases +# prefixed by the word `Australian' when referring to local times; +# time announcements on that service, naturally enough, are made in UTC. + +# From Arthur David Olson (March 8 1992): +# Given the above, what's chosen for year-round use is: +# CST for any place operating at a GMTOFF of 9:30 +# WST for any place operating at a GMTOFF of 8:00 +# EST for any place operating at a GMTOFF of 10:00 + +# From Paul Eggert (November 8, 1994): +# Shanks reports 2:00 for all autumn changes in Australia and New Zealand. +# Mark Prior <mrp@itd.adelaide.edu.au> writes that his newspaper +# reports that NSW's fall 1995 change will occur at 2:00, +# but Robert Elz says it's been 3:00 in Victoria since 1970 +# and perhaps the newspaper's `2:00' is referring to standard time. +# And Robert Uzgalis <buz@cs.aukuni.ac.nz> says that the New Zealand Daylight +# Savings Time Order in Council dated 1990-06-18 specifies 2:00 standard +# time on both the first Sunday in October and the third Sunday in March. +# For now we'll continue to assume 3:00 for changes since 1970. + +# Northern Territory + +# From George Shepherd via Simon Woodhead via Robert Elz (March 6, 1991): +# # The NORTHERN TERRITORY..

On 1847 Sep 22 the +# Railway Clearing House, an industry standards body, recommended that GMT be +# adopted at all stations; the January 1848 Bradshaw's lists most major +# railways as using GMT. By 1855 the vast majority of public +# clocks in Britain were set to GMT (though some, like the Great Clock +# in Tom Tower at Christ Church, Oxford, were fitted with two minute hands, +# one for local time and one for GMT). The last major holdout was the legal +# system, which stubbornly stuck to local time for many years, leading +# to oddities like polls opening at 08:13 and closing at 16:13. +# The legal system finally switched to GMT when the Statutes (Definition +# of Time) Act took effect; it received the Royal Assent on 1880 Aug 2. +# +# In the tables below, we condense this complicated story into a single +# transition date for London, namely 1847 Sep 22.

The default interpretation of Acts is that they apply +# throughout the UK. +# +# With that, I rest my case Milud :-) +# +# Thanks are due to my learned legal friend Lorna Montgomerie, who dug out +# the dusty old statutes, and to Melanie Allison of the Ministry of Defence, +# who provided the wartime regulations and a snippet of Hansard explaining +# why double summer time started on a Monday in 1945 (it was Easter). + +# From Peter Ilieve <peter@memex.co.uk> (November 18, 1993) +# +# Here is a revised version of my tabrules file for the perl script I sent +# before.

This is an interesting case as the first Order gave a +# different date of 7 April 1967 for the Isle of Man but this was changed +# before it came into effect by another Order for the Isle of Man alone. +# +# I don't think I will be able to find any more of the earlier Orders. +# The annual volumes for 1949--52 do not contain the various Summer Time +# Orders. They therefore don't appear in the index.

In 1965 a provincial +# referendum favoured legislating common time practices. +# +# On 15 April 1966 the Time Act (c. T-14, Revised Statutes of +# Saskatchewan 1978) was proclaimed, and established that the eastern +# part of Saskatchewan would use CST year round, that districts in +# northwest Saskatchewan would by default follow CST but could opt to +# follow Mountain Time rules (thus 1 hour difference in the winter and +# zero in the summer), and that districts in southwest Saskatchewan would +# by default follow MT but could opt to follow CST. +# +# It took a few years for the dust to settle (I know one story of a town +# on one time zone having its school in another, such that a mom had to +# serve her family lunch in two shifts), but presently it seems that only +# a few towns on the border with Alberta (e.g. Lloydminster) follow MT +# rules any more; all other districts appear to have used CST year round +# since sometime in the 1960s. +# +# Here's how I would summarize things.

Any +# current exceptions can put themselves in the "Mountain" zone, since +# those are the rules they follow.
