Announcers 8082742Swollman# on its overseas service, Radio Australia, use the same phrases 8092742Swollman# prefixed by the word `Australian' when referring to local times; 8102742Swollman# time announcements on that service, naturally enough, are made in UTC. 8112742Swollman 81286222Swollman# From Arthur David Olson (1992-03-08): 8132742Swollman# Given the above, what's chosen for year-round use is: 8142742Swollman# CST for any place operating at a GMTOFF of 9:30 8152742Swollman# WST for any place operating at a GMTOFF of 8:00 8162742Swollman# EST for any place operating at a GMTOFF of 10:00 8172742Swollman 818163302Sru# From Chuck Soper (2006-06-01): 819163302Sru# I recently found this Australian government web page on time zones: 820163302Sru# <http://www.australia.gov.au/about-australia-13time> 821163302Sru# And this government web page lists time zone names and abbreviations: 822163302Sru# <http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml> 823163302Sru 82486222Swollman# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST" 82586222Swollman# versus "AEST" etc.: 82686222Swollman# 82786222Swollman# I see the following points of dispute: 82886222Swollman# 82986222Swollman# * How important are unique time zone abbreviations? 83086222Swollman# 83186222Swollman# Here I tend to agree with the point (most recently made by Chris 83286222Swollman# Newman) that unique abbreviations should not be essential for proper 83386222Swollman# operation of software. We have other instances of ambiguity 83486222Swollman# (e.g. "IST" denoting both "Israel Standard Time" and "Indian 83586222Swollman# Standard Time"), and they are not likely to go away any time soon. 83686222Swollman# In the old days, some software mistakenly relied on unique 83786222Swollman# abbreviations, but this is becoming less true with time, and I don't 83886222Swollman# think it's that important to cater to such software these days. 83986222Swollman# 84086222Swollman# On the other hand, there is another motivation for unambiguous 84186222Swollman# abbreviations: it cuts down on human confusion. This is 84286222Swollman# particularly true for Australia, where "EST" can mean one thing for 84386222Swollman# time T and a different thing for time T plus 1 second. 84486222Swollman# 84586222Swollman# * Does the relevant legislation indicate which abbreviations should be used? 84686222Swollman# 84786222Swollman# Here I tend to think that things are a mess, just as they are in 84886222Swollman# many other countries. We Americans are currently disagreeing about 84986222Swollman# which abbreviation to use for the newly legislated Chamorro Standard 85086222Swollman# Time, for example. 85186222Swollman# 85286222Swollman# Personally, I would prefer to use common practice; I would like to 85386222Swollman# refer to legislation only for examples of common practice, or as a 85486222Swollman# tiebreaker. 85586222Swollman# 85686222Swollman# * Do Australians more often use "Eastern Daylight Time" or "Eastern 85786222Swollman# Summer Time"? Do they typically prefix the time zone names with 85886222Swollman# the word "Australian"? 85986222Swollman# 86086222Swollman# My own impression is that both "Daylight Time" and "Summer Time" are 86186222Swollman# common and are widely understood, but that "Summer Time" is more 86286222Swollman# popular; and that the leading "A" is also common but is omitted more 86386222Swollman# often than not. I just used AltaVista advanced search and got the 86486222Swollman# following count of page hits: 86586222Swollman# 86686222Swollman# 1,103 "Eastern Summer Time" AND domain:au 86786222Swollman# 971 "Australian Eastern Summer Time" AND domain:au 86886222Swollman# 613 "Eastern Daylight Time" AND domain:au 86986222Swollman# 127 "Australian Eastern Daylight Time" AND domain:au 87086222Swollman# 87186222Swollman# Here "Summer" seems quite a bit more popular than "Daylight", 87286222Swollman# particularly when we know the time zone is Australian and not US, 87386222Swollman# say. The "Australian" prefix seems to be popular for Eastern Summer 87486222Swollman# Time, but unpopular for Eastern Daylight Time. 87586222Swollman# 87686222Swollman# For abbreviations, tools like AltaVista are less useful because of 87786222Swollman# ambiguity. Many hits are not really time zones, unfortunately, and 87886222Swollman# many hits denote US time zones and not Australian ones. But here 87986222Swollman# are the hit counts anyway: 88086222Swollman# 88186222Swollman# 161,304 "EST" and domain:au 88286222Swollman# 25,156 "EDT" and domain:au 88386222Swollman# 18,263 "AEST" and domain:au 88486222Swollman# 10,416 "AEDT" and domain:au 88586222Swollman# 88686222Swollman# 14,538 "CST" and domain:au 88786222Swollman# 5,728 "CDT" and domain:au 88886222Swollman# 176 "ACST" and domain:au 88986222Swollman# 29 "ACDT" and domain:au 89086222Swollman# 89186222Swollman# 7,539 "WST" and domain:au 89286222Swollman# 68 "AWST" and domain:au 89386222Swollman# 89486222Swollman# This data suggest that Australians tend to omit the "A" prefix in 89586222Swollman# practice. The situation for "ST" versus "DT" is less clear, given 89686222Swollman# the ambiguities involved. 89786222Swollman# 89886222Swollman# * How do Australians feel about the abbreviations in the tz database? 89986222Swollman# 90086222Swollman# If you just count Australians on this list, I count 2 in favor and 3 90186222Swollman# against. One of the "against" votes (David Keegel) counseled delay, 90286222Swollman# saying that both AEST/AEDT and EST/EST are widely used and 90386222Swollman# understood in Australia. 90486222Swollman 90514343Swollman# From Paul Eggert (1995-12-19): 906158421Swollman# Shanks & Pottenger report 2:00 for all autumn changes in Australia and NZ. 907149514Swollman# Mark Prior writes that his newspaper 9089908Swollman# reports that NSW's fall 1995 change will occur at 2:00, 9099908Swollman# but Robert Elz says it's been 3:00 in Victoria since 1970 9109908Swollman# and perhaps the newspaper's `2:00' is referring to standard time. 91114343Swollman# For now we'll continue to assume 2:00s for changes since 1960. 9122742Swollman 913149514Swollman# From Eric Ulevik (1998-01-05): 91475267Swollman# 91543014Swollman# Here are some URLs to Australian time legislation.

Mapmakers are free to draw it as they please. 163658787Sru# Reputable mapmakers will simply ensure that every point of land appears on 163758787Sru# the correct side of the IDL, according to the date legally observed there. 163858787Sru# 163958787Sru# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and 164058787Sru# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL 164158787Sru# to the east side of the Phoenix and Line Islands), I suppose that most 164258787Sru# mapmakers redrew the IDL following the boundary of Kiribati. Even that line 164358787Sru# has a rather arbitrary nature. The straight-line boundaries between Pacific 164458787Sru# island nations that are shown on many maps are based on an international 1645153670Swollman# convention, but are not legally binding national borders.... The date is 164658787Sru# governed by the IDL; therefore, even on the high seas, there may be some 164758787Sru# places as late as fourteen hours later than UTC. And, since the IDL is not 164858787Sru# an international standard, there are some places on the high seas where the 164958787Sru# correct date is ambiguous. 1650149514Swollman 1651153670Swollman# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31): 1652153670Swollman# Before 1920, all ships kept local apparent time on the high seas by setting 1653153670Swollman# their clocks at night or at the morning sight so that, given the ship's 1654153670Swollman# speed and direction, it would be 12 o'clock when the Sun crossed the ship's 1655153670Swollman# meridian (12 o'clock = local apparent noon). During 1917, at the 1656153670Swollman# Anglo-French Conference on Time-keeping at Sea, it was recommended that all 1657153670Swollman# ships, both military and civilian, should adopt hourly standard time zones 1658153670Swollman# on the high seas. Whenever a ship was within the territorial waters of any 1659153670Swollman# nation it would use that nation's standard time. The captain was permitted 1660153670Swollman# to change his ship's clocks at a time of his choice following his ship's 1661153670Swollman# entry into another zone time--he often chose midnight. These zones were 1662153670Swollman# adopted by all major fleets between 1920 and 1925 but not by many 1663153670Swollman# independent merchant ships until World War II. 1664153670Swollman 1665149514Swollman# From Paul Eggert, using references suggested by Oscar van Vlijmen 1666149514Swollman# (2005-03-20): 1667149514Swollman# 1668149514Swollman# The American Practical Navigator (2002) 1669149514Swollman# <http://pollux.nss.nima.mil/pubs/pubs_j_apn_sections.html?rid=187> 1670149514Swollman# talks only about the 180-degree meridian with respect to ships in 1671149514Swollman# international waters; it ignores the international date line. 1672
