Now by a happy coincidence, `summer' 9142742Swollman# and `standard' happen to start with the same letter; hence, the 9152742Swollman# abbreviation does _not_ change... 9162742Swollman# The legislation does not actually define abbreviations, at least 9172742Swollman# in this State, but the abbreviation is just commonly taken to be the 9182742Swollman# initials of the phrase, and the legislation here uniformly uses 9192742Swollman# the phrase `summer time' and does not use the phrase `daylight 9202742Swollman# time'. 9212742Swollman# Announcers on the Commonwealth radio network, the ABC (for Australian 9222742Swollman# Broadcasting Commission), use the phrases `Eastern Standard Time' 9232742Swollman# or `Eastern Summer Time'. (Note, though, that as I say in the 9242742Swollman# current australasia file, there is really no such thing.) Announcers 9252742Swollman# on its overseas service, Radio Australia, use the same phrases 9262742Swollman# prefixed by the word `Australian' when referring to local times; 9272742Swollman# time announcements on that service, naturally enough, are made in UTC. 9282742Swollman 92986222Swollman# From Arthur David Olson (1992-03-08): 9302742Swollman# Given the above, what's chosen for year-round use is: 9312742Swollman# CST for any place operating at a GMTOFF of 9:30 9322742Swollman# WST for any place operating at a GMTOFF of 8:00 9332742Swollman# EST for any place operating at a GMTOFF of 10:00 9342742Swollman 935163302Sru# From Chuck Soper (2006-06-01): 936163302Sru# I recently found this Australian government web page on time zones: 937163302Sru# <http://www.australia.gov.au/about-australia-13time> 938163302Sru# And this government web page lists time zone names and abbreviations: 939163302Sru# <http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml> 940163302Sru 94186222Swollman# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST" 94286222Swollman# versus "AEST" etc.: 94386222Swollman# 94486222Swollman# I see the following points of dispute: 94586222Swollman# 94686222Swollman# * How important are unique time zone abbreviations? 94786222Swollman# 94886222Swollman# Here I tend to agree with the point (most recently made by Chris 94986222Swollman# Newman) that unique abbreviations should not be essential for proper 95086222Swollman# operation of software. We have other instances of ambiguity 95186222Swollman# (e.g. "IST" denoting both "Israel Standard Time" and "Indian 95286222Swollman# Standard Time"), and they are not likely to go away any time soon. 95386222Swollman# In the old days, some software mistakenly relied on unique 95486222Swollman# abbreviations, but this is becoming less true with time, and I don't 95586222Swollman# think it's that important to cater to such software these days. 95686222Swollman# 95786222Swollman# On the other hand, there is another motivation for unambiguous 95886222Swollman# abbreviations: it cuts down on human confusion. This is 95986222Swollman# particularly true for Australia, where "EST" can mean one thing for 96086222Swollman# time T and a different thing for time T plus 1 second. 96186222Swollman# 96286222Swollman# * Does the relevant legislation indicate which abbreviations should be used? 96386222Swollman# 96486222Swollman# Here I tend to think that things are a mess, just as they are in 96586222Swollman# many other countries. We Americans are currently disagreeing about 96686222Swollman# which abbreviation to use for the newly legislated Chamorro Standard 96786222Swollman# Time, for example. 96886222Swollman# 96986222Swollman# Personally, I would prefer to use common practice; I would like to 97086222Swollman# refer to legislation only for examples of common practice, or as a 97186222Swollman# tiebreaker. 97286222Swollman# 97386222Swollman# * Do Australians more often use "Eastern Daylight Time" or "Eastern 97486222Swollman# Summer Time"? Do they typically prefix the time zone names with 97586222Swollman# the word "Australian"? 97686222Swollman# 97786222Swollman# My own impression is that both "Daylight Time" and "Summer Time" are 97886222Swollman# common and are widely understood, but that "Summer Time" is more 97986222Swollman# popular; and that the leading "A" is also common but is omitted more 98086222Swollman# often than not. I just used AltaVista advanced search and got the 98186222Swollman# following count of page hits: 98286222Swollman# 98386222Swollman# 1,103 "Eastern Summer Time" AND domain:au 98486222Swollman# 971 "Australian Eastern Summer Time" AND domain:au 98586222Swollman# 613 "Eastern Daylight Time" AND domain:au 98686222Swollman# 127 "Australian Eastern Daylight Time" AND domain:au 98786222Swollman# 98886222Swollman# Here "Summer" seems quite a bit more popular than "Daylight", 98986222Swollman# particularly when we know the time zone is Australian and not US, 99086222Swollman# say. The "Australian" prefix seems to be popular for Eastern Summer 99186222Swollman# Time, but unpopular for Eastern Daylight Time. 99286222Swollman# 99386222Swollman# For abbreviations, tools like AltaVista are less useful because of 99486222Swollman# ambiguity. Many hits are not really time zones, unfortunately, and 99586222Swollman# many hits denote US time zones and not Australian ones. But here 99686222Swollman# are the hit counts anyway: 99786222Swollman# 99886222Swollman# 161,304 "EST" and domain:au 99986222Swollman# 25,156 "EDT" and domain:au 100086222Swollman# 18,263 "AEST" and domain:au 100186222Swollman# 10,416 "AEDT" and domain:au 100286222Swollman# 100386222Swollman# 14,538 "CST" and domain:au 100486222Swollman# 5,728 "CDT" and domain:au 100586222Swollman# 176 "ACST" and domain:au 100686222Swollman# 29 "ACDT" and domain:au 100786222Swollman# 100886222Swollman# 7,539 "WST" and domain:au 100986222Swollman# 68 "AWST" and domain:au 101086222Swollman# 101186222Swollman# This data suggest that Australians tend to omit the "A" prefix in 101286222Swollman# practice. The situation for "ST" versus "DT" is less clear, given 101386222Swollman# the ambiguities involved. 101486222Swollman# 101586222Swollman# * How do Australians feel about the abbreviations in the tz database? 101686222Swollman# 101786222Swollman# If you just count Australians on this list, I count 2 in favor and 3 101886222Swollman# against. One of the "against" votes (David Keegel) counseled delay, 101986222Swollman# saying that both AEST/AEDT and EST/EST are widely used and 102086222Swollman# understood in Australia. 102186222Swollman 102214343Swollman# From Paul Eggert (1995-12-19): 1023158421Swollman# Shanks & Pottenger report 2:00 for all autumn changes in Australia and NZ. 1024149514Swollman# Mark Prior writes that his newspaper 10259908Swollman# reports that NSW's fall 1995 change will occur at 2:00, 10269908Swollman# but Robert Elz says it's been 3:00 in Victoria since 1970 10279908Swollman# and perhaps the newspaper's `2:00' is referring to standard time. 102814343Swollman# For now we'll continue to assume 2:00s for changes since 1960. 10292742Swollman 1030149514Swollman# From Eric Ulevik (1998-01-05): 103175267Swollman# 103243014Swollman# Here are some URLs to Australian time legislation.

The time was all the 1734121098Swollman# more confusing at that point, because we had crossed the 1735121098Swollman# International Date Line, thus getting two Sundays. Furthermore, we 1736121098Swollman# discovered that Wake Island had two hours of daylight saving time 1737121098Swollman# making calculation of time in Washington difficult if not almost 1738121098Swollman# impossible. 1739121098Swollman# 1740121098Swollman# http://www.trumanlibrary.org/wake/meeting.htm 1741121098Swollman 1742121098Swollman# From Paul Eggert (2003-03-23): 1743121098Swollman# We have no other report of DST in Wake Island, so omit this info for now. 1744121098Swollman 174558787Sru############################################################################### 174658787Sru 174758787Sru# The International Date Line 174858787Sru 174958787Sru# From Gwillim Law (2000-01-03): 175075267Swollman# 175158787Sru# The International Date Line is not defined by any international standard, 175258787Sru# convention, or treaty. Mapmakers are free to draw it as they please. 175358787Sru# Reputable mapmakers will simply ensure that every point of land appears on 175458787Sru# the correct side of the IDL, according to the date legally observed there. 175558787Sru# 175658787Sru# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and 175758787Sru# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL 175858787Sru# to the east side of the Phoenix and Line Islands), I suppose that most 175958787Sru# mapmakers redrew the IDL following the boundary of Kiribati. Even that line 176058787Sru# has a rather arbitrary nature. The straight-line boundaries between Pacific 176158787Sru# island nations that are shown on many maps are based on an international 1762153670Swollman# convention, but are not legally binding national borders.... The date is 176358787Sru# governed by the IDL; therefore, even on the high seas, there may be some 176458787Sru# places as late as fourteen hours later than UTC. And, since the IDL is not 176558787Sru# an international standard, there are some places on the high seas where the 176658787Sru# correct date is ambiguous. 1767149514Swollman 1768153670Swollman# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31): 1769153670Swollman# Before 1920, all ships kept local apparent time on the high seas by setting 1770153670Swollman# their clocks at night or at the morning sight so that, given the ship's 1771153670Swollman# speed and direction, it would be 12 o'clock when the Sun crossed the ship's 1772153670Swollman# meridian (12 o'clock = local apparent noon). During 1917, at the 1773153670Swollman# Anglo-French Conference on Time-keeping at Sea, it was recommended that all 1774153670Swollman# ships, both military and civilian, should adopt hourly standard time zones 1775153670Swollman# on the high seas. Whenever a ship was within the territorial waters of any 1776153670Swollman# nation it would use that nation's standard time. The captain was permitted 1777153670Swollman# to change his ship's clocks at a time of his choice following his ship's 1778153670Swollman# entry into another zone time--he often chose midnight. These zones were 1779153670Swollman# adopted by all major fleets between 1920 and 1925 but not by many 1780153670Swollman# independent merchant ships until World War II. 1781153670Swollman 1782149514Swollman# From Paul Eggert, using references suggested by Oscar van Vlijmen 1783149514Swollman# (2005-03-20): 1784149514Swollman# 1785149514Swollman# The American Practical Navigator (2002) 1786149514Swollman# <http://pollux.nss.nima.mil/pubs/pubs_j_apn_sections.html?rid=187> 1787149514Swollman# talks only about the 180-degree meridian with respect to ships in 1788149514Swollman# international waters; it ignores the international date line. 1789
