It was never formally annexed to Egypt, # though. # # The rest of Palestine was under Jordanian rule at that time, formally # annexed in 1950 as the West Bank (and the word "Trans" was dropped from # the country's previous name of "the Hashemite Kingdom of the # Trans-Jordan"). So the rules for Jordan for that time apply. Major # towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and # East Jerusalem. # # Both areas were occupied by Israel in June 1967, but not annexed (except # for East Jerusalem). They were on Israel time since then; there might # have been a Military Governor's order about time zones, but I'm not aware # of any (such orders may have been issued semi-annually whenever summer # time was in effect, but maybe the legal aspect of time was just neglected). # # The Palestinian Authority was established in 1993, and got hold of most # towns in the West Bank and Gaza by 1995. I know that in order to # demonstrate...independence, they have been switching to # summer time and back on a different schedule than Israel's, but I don't # know when this was started, or what algorithm is used (most likely the # Jordanian one). # # To summarize, the table should probably look something like that: # # Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996- # ------------+-----------+-----------+-----------+----------- # Israel | Zion | Zion | Zion | Zion # West bank | Zion | Jordan | Zion | Jordan # Gaza | Zion | Egypt | Zion | Jordan # # I guess more info may be available from the PA's web page (if/when they # have one). # From Paul Eggert (1998-02-25): # Shanks writes that Gaza did not observe DST until 1957, but we'll go # with Shapir and assume that it observed DST from 1940 through 1947, # and that it used Jordanian rules starting in 1996. # We don't yet need a separate entry for the West Bank, since # the only differences between it and Gaza that we know about # occurred before our cutoff date of 1970. # However, as we get more information, we may need to add entries # for parts of the West Bank as they transitioned from Israel's rules # to Palestine's rules.

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 (1992-03-08): # 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 (2001-04-05), summarizing a long discussion about "EST" # versus "AEST" etc.: # # I see the following points of dispute: # # * How important are unique time zone abbreviations? # # Here I tend to agree with the point (most recently made by Chris # Newman) that unique abbreviations should not be essential for proper # operation of software. We have other instances of ambiguity # (e.g. "IST" denoting both "Israel Standard Time" and "Indian # Standard Time"), and they are not likely to go away any time soon. # In the old days, some software mistakenly relied on unique # abbreviations, but this is becoming less true with time, and I don't # think it's that important to cater to such software these days. # # On the other hand, there is another motivation for unambiguous # abbreviations: it cuts down on human confusion. This is # particularly true for Australia, where "EST" can mean one thing for # time T and a different thing for time T plus 1 second. # # * Does the relevant legislation indicate which abbreviations should be used? # # Here I tend to think that things are a mess, just as they are in # many other countries. We Americans are currently disagreeing about # which abbreviation to use for the newly legislated Chamorro Standard # Time, for example. # # Personally, I would prefer to use common practice; I would like to # refer to legislation only for examples of common practice, or as a # tiebreaker. # # * Do Australians more often use "Eastern Daylight Time" or "Eastern # Summer Time"? Do they typically prefix the time zone names with # the word "Australian"? # # My own impression is that both "Daylight Time" and "Summer Time" are # common and are widely understood, but that "Summer Time" is more # popular; and that the leading "A" is also common but is omitted more # often than not. I just used AltaVista advanced search and got the # following count of page hits: # # 1,103 "Eastern Summer Time" AND domain:au # 971 "Australian Eastern Summer Time" AND domain:au # 613 "Eastern Daylight Time" AND domain:au # 127 "Australian Eastern Daylight Time" AND domain:au # # Here "Summer" seems quite a bit more popular than "Daylight", # particularly when we know the time zone is Australian and not US, # say. The "Australian" prefix seems to be popular for Eastern Summer # Time, but unpopular for Eastern Daylight Time. # # For abbreviations, tools like AltaVista are less useful because of # ambiguity. Many hits are not really time zones, unfortunately, and # many hits denote US time zones and not Australian ones. But here # are the hit counts anyway: # # 161,304 "EST" and domain:au # 25,156 "EDT" and domain:au # 18,263 "AEST" and domain:au # 10,416 "AEDT" and domain:au # # 14,538 "CST" and domain:au # 5,728 "CDT" and domain:au # 176 "ACST" and domain:au # 29 "ACDT" and domain:au # # 7,539 "WST" and domain:au # 68 "AWST" and domain:au # # This data suggest that Australians tend to omit the "A" prefix in # practice. The situation for "ST" versus "DT" is less clear, given # the ambiguities involved. # # * How do Australians feel about the abbreviations in the tz database? # # If you just count Australians on this list, I count 2 in favor and 3 # against. One of the "against" votes (David Keegel) counseled delay, # saying that both AEST/AEDT and EST/EST are widely used and # understood in Australia. # From Paul Eggert (1995-12-19): # Shanks reports 2:00 for all autumn changes in Australia and New Zealand. # Mark Prior 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. # For now we'll continue to assume 2:00s for changes since 1960. # From Eric Ulevik (1998-01-05): # # Here are some URLs to Australian time legislation.

The primary town is Madura, with the other towns being +# Mundrabilla and Eucla. According to the sheriff of Madura, the +# residents got tired of having to change the time so often, as they are +# located in a strip overlapping the border of South Australia and Western +# Australia. South Australia observes daylight saving time; Western +# Australia does not. The two states are one and a half hours apart. The +# residents decided to forget about this nonsense of changing the clock so +# much and set the local time 20 hours and 45 minutes from the +# international date line, or right in the middle of the time of South +# Australia and Western Australia. As it only affects about 10 people and +# tourists staying at the Madura Motel, it has never really made as big an +# impact as Broken Hill. However, as tourist visiting there or anyone +# calling the local sheriff will attest, they do keep time in this way. +# +# From Paul Eggert (2002-04-09): +# This is confirmed by the section entitled +# "What's the deal with time zones???" in +# , +# which says a few other things: +# +# * Border Village, SA also is 45 minutes ahead of Perth. +# * The locals call this time zone "central W.A.

And if you go there on Nov. 11, at 11am local time, # you will indeed see the sunbeam illuminate the special spot at the # expected time. # # However, that is only because of some special mirror contraption that had # to be employed, since due to daylight savings time, the true solar time of # the remembrance moment occurs one hour later (or earlier?).

For your information the # Lord Howe Island Board (controlling authority for the Island) is # seeking the community's views on various options for summer time # arrangements on the Island, e.g. advance clocks by 1 full hour # instead of only 30 minutes.

The starting date for summer time on the Island will # however always coincide with the rest of NSW. # From James Lonergan, Secretary, Lord Howe Island Board (2000-10-25): # Lord Howe Island advances clocks by 30 minutes during DST in NSW and retards # clocks by 30 minutes when DST finishes. Since DST was most recently # introduced in NSW, the "changeover" time on the Island has been 02:00 as # shown on clocks on LHI.

"If at midnight on Dec. 31, we move ahead 40 # minutes, as your Royal Highness wishes, what becomes of the 40 # minutes we have lost?" # # The Crown Prince, presented an unanswerable argument: "Remember that # on the World Day of Prayer, you would be the first people on Earth # to say your prayers in the morning." # From Paul Eggert (1999-08-12): # Shanks says the transition was on 1968-10-01; go with Mundell. # From Eric Ulevik (1999-05-03): # Tonga's director of tourism, who is also secretary of the National Millenium # Committee, has a plan to get Tonga back in front. # He has proposed a one-off move to tropical daylight saving for Tonga from # October to March, which has won approval in principle from the Tongan # Government. # From Steffen Thorsen [straen@thorsen.priv.no] (1999-09-09): # * Tonga will introduce DST in November # # I was given this link by John Letts : # # http://news.bbc.co.uk/hi/english/world/asia-pacific/newsid_424000/424764.stm # # # I have not been able to find exact dates for the transition in November # yet.

Each issue from then until # 9/95 says that DST is observed only in the ten states I quoted from 9/95, # along with Mato Grosso (MT) and Mato Grosso do Sul (MS), which are in BR2 # (UTC-4).... The other two time zones given for Brazil are BR3, which is # UTC-5, no DST, and applies only in the state of Acre (AC); and BR4, which is # UTC-2, and applies to Fernando de Noronha (formerly FN, but I believe it's # become part of the state of Pernambuco). The boundary between BR1 and BR2 # has never been clearly stated. They've simply been called East and West. # However, some conclusions can be drawn from another IATA manual: the Airline # Coding Directory, which lists close to 400 airports in Brazil. For each # airport it gives a time zone which is coded to the SSIM. From that # information, I'm led to conclude that the states of Amapa (AP), Ceara (CE), # Maranhao (MA), Paraiba (PR), Pernambuco (PE), Piaui (PI), and Rio Grande do # Norte (RN), and the eastern part of Para (PA) are all in BR1 without DST. # From Marcos Tadeu (1998-09-27): # # Brazilian official page # # From Jesper Norgaard (2000-11-03): # [For an official list of which regions in Brazil use which time zones, see:] # http://pcdsh01.on.br/Fusbr.htm # http://pcdsh01.on.br/Fusbrhv.htm -# From Paul Eggert (2000-10-02): -# The official decrees referenced below are taken from +# From Celso Doria via David Madeo (2002-10-09): +# The reason for the delay this year has to do with elections in Brazil. +# +# Unlike in the United States, elections in Brazil are 100% computerized and +# the results are known almost immediately.

Here is # what was said then: # # "The general rule was that Stanley used daylight saving and the Camp # did not. However for various reasons many people in the Camp have # started to use daylight saving (known locally as 'Stanley Time') # There is no rule as to who uses daylight saving - it is a matter of # personal choice and so it is impossible to draw a map showing who # uses it and who does not. Any list would be out of date as soon as # it was produced. This year daylight saving ended on April 18/19th # and started again on September 12/13th. I do not know what the rule # is, but can find out if you like. We do not change at the same time # as UK or Chile." # # I did have in my notes that the rule was "Second Saturday in Sep at # 0:00 until third Saturday in Apr at 0:00". I think that this does # not agree in some cases with Shanks; is this true? # # Also, there is no mention in the list that some areas in the # Falklands do not use DST. I have found in my communications there # that these areas are on the western half of East Falkland and all of # West Falkland. Stanley is the only place that consistently observes # DST. Again, as in other places in the world, the farmers don't like # it. West Falkland is almost entirely sheep farmers. # # I know one lady there that keeps a list of which farm keeps DST and # which doesn't each year. She runs a shop in Stanley, and says that # the list changes each year. She uses it to communicate to her # customers, catching them when they are home for lunch or dinner. # From Paul Eggert (2001-03-05): # For now, we'll just record the time in Stanley, since we have no # better info. # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Falk 1937 1938 - Sep lastSun 0:00 1:00 S Rule Falk 1938 1942 - Mar Sun>=19 0:00 0 - Rule Falk 1939 only - Oct 1 0:00 1:00 S Rule Falk 1940 1942 - Sep lastSun 0:00 1:00 S Rule Falk 1943 only - Jan 1 0:00 0 - Rule Falk 1983 only - Sep lastSun 0:00 1:00 S Rule Falk 1984 1985 - Apr lastSun 0:00 0 - Rule Falk 1984 only - Sep 16 0:00 1:00 S Rule Falk 1985 2000 - Sep Sun>=9 0:00 1:00 S Rule Falk 1986 2000 - Apr Sun>=16 0:00 0 - Rule Falk 2001 max - Apr Sun>=15 2:00 0 - Rule Falk 2001 max - Sep Sun>=1 2:00 1:00 S # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Atlantic/Stanley -3:51:24 - LMT 1890 -3:51:24 - SMT 1912 Mar 12 # Stanley Mean Time -4:00 Falk FK%sT 1983 May # Falkland Is Time -3:00 Falk FK%sT 1985 Sep 15 -4:00 Falk FK%sT # French Guiana # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone America/Cayenne -3:29:20 - LMT 1911 Jul -4:00 - GFT 1967 Oct # French Guiana Time -3:00 - GFT # Guyana # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone America/Guyana -3:52:40 - LMT 1915 Mar # Georgetown -3:45 - GBGT 1966 May 26 # Br Guiana Time -3:45 - GYT 1975 Jul 31 # Guyana Time -3:00 - GYT 1991 # IATA SSIM (1996-06) says -4:00.
