531:   # 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): + # 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 <mrp@itd.adelaide.edu.au> writes that his newspaper
651:   # From Arthur David Olson (1992-03-08):   # The chosen rules the union of the 1971/1972 change and the 1989-1992 changes.    + # From Rives McDow (2002-04-09): + # The most interesting region I have found consists of three towns on the + # southern coast of Australia, population 10 at last report, along with + # 50,000 sheep, about 100 kilometers long and 40 kilometers into the + # continent. 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 + # <http://www.earthsci.unimelb.edu.au/~awatkins/null.html>, + # 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. Time" (presumably "CWAT"). + # * The locals also call Western Australia time "Perth time". + # + # It's not clear from context whether everyone in Western Australia + # knows of this naming convention, or whether it's just the people in + # this subregion. +    # South Australia, Tasmania, Victoria      # From Arthur David Olson (1992-03-08):
752:   # # The state of VICTORIA.. [ Courtesy of Vic. Dept of Premier + Cabinet ]   # # [ Nov 1990 ]    + # From Scott Harrington (2001-08-29): + # On KQED's "City Arts and Lectures" program last night I heard an + # interesting story about daylight savings time. Dr. John Heilbron was + # discussing his book "The Sun in the Church: Cathedrals as Solar + # Observatories"[1], and in particular the Shrine of Remembrance[2] located + # in Melbourne, Australia. + # + # Apparently the shrine's main purpose is a beam of sunlight which + # illuminates a special spot on the floor at the 11th hour of the 11th day + # of the 11th month (Remembrance Day) every year in memory of Australia's + # fallen WWI soldiers. 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?). Perhaps + # someone with more information on this jury-rig can tell us more. + # + # [1] http://www.hup.harvard.edu/catalog/HEISUN.html + # [2] http://www.shrine.org.au +    # New South Wales      # From Arthur David Olson:
