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 Chuck Soper (2006-06-01): -# I recently found this Australian government web page on time zones: -# <http://www.australia.gov.au/about-australia-13time> -# And this government web page lists time zone names and abbreviations: -# <http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml> - -# 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 & Pottenger report 2:00 for all autumn changes in Australia and NZ. -# 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.

Mapmakers are free to draw it as they please. -# Reputable mapmakers will simply ensure that every point of land appears on -# the correct side of the IDL, according to the date legally observed there. -# -# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and -# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL -# to the east side of the Phoenix and Line Islands), I suppose that most -# mapmakers redrew the IDL following the boundary of Kiribati. Even that line -# has a rather arbitrary nature. The straight-line boundaries between Pacific -# island nations that are shown on many maps are based on an international -# convention, but are not legally binding national borders.... The date is -# governed by the IDL; therefore, even on the high seas, there may be some -# places as late as fourteen hours later than UTC. And, since the IDL is not -# an international standard, there are some places on the high seas where the -# correct date is ambiguous. - -# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31): -# Before 1920, all ships kept local apparent time on the high seas by setting -# their clocks at night or at the morning sight so that, given the ship's -# speed and direction, it would be 12 o'clock when the Sun crossed the ship's -# meridian (12 o'clock = local apparent noon). During 1917, at the -# Anglo-French Conference on Time-keeping at Sea, it was recommended that all -# ships, both military and civilian, should adopt hourly standard time zones -# on the high seas. Whenever a ship was within the territorial waters of any -# nation it would use that nation's standard time. The captain was permitted -# to change his ship's clocks at a time of his choice following his ship's -# entry into another zone time--he often chose midnight. These zones were -# adopted by all major fleets between 1920 and 1925 but not by many -# independent merchant ships until World War II. - -# From Paul Eggert, using references suggested by Oscar van Vlijmen -# (2005-03-20): -# -# The American Practical Navigator (2002) -# <http://pollux.nss.nima.mil/pubs/pubs_j_apn_sections.html?rid=187> -# talks only about the 180-degree meridian with respect to ships in -# international waters; it ignores the international date line. |
