Now by a happy coincidence, `summer' 6032742Swollman# and `standard' happen to start with the same letter; hence, the 6042742Swollman# abbreviation does _not_ change... 6052742Swollman# The legislation does not actually define abbreviations, at least 6062742Swollman# in this State, but the abbreviation is just commonly taken to be the 6072742Swollman# initials of the phrase, and the legislation here uniformly uses 6082742Swollman# the phrase `summer time' and does not use the phrase `daylight 6092742Swollman# time'. 6102742Swollman# Announcers on the Commonwealth radio network, the ABC (for Australian 6112742Swollman# Broadcasting Commission), use the phrases `Eastern Standard Time' 6122742Swollman# or `Eastern Summer Time'. (Note, though, that as I say in the 6132742Swollman# current australasia file, there is really no such thing.) Announcers 6142742Swollman# on its overseas service, Radio Australia, use the same phrases 6152742Swollman# prefixed by the word `Australian' when referring to local times; 6162742Swollman# time announcements on that service, naturally enough, are made in UTC. 6172742Swollman 61886222Swollman# From Arthur David Olson (1992-03-08): 6192742Swollman# Given the above, what's chosen for year-round use is: 6202742Swollman# CST for any place operating at a GMTOFF of 9:30 6212742Swollman# WST for any place operating at a GMTOFF of 8:00 6222742Swollman# EST for any place operating at a GMTOFF of 10:00 6232742Swollman 624163302Sru# From Chuck Soper (2006-06-01): 625163302Sru# I recently found this Australian government web page on time zones: 626163302Sru# <http://www.australia.gov.au/about-australia-13time> 627163302Sru# And this government web page lists time zone names and abbreviations: 628163302Sru# <http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml> 629163302Sru 63086222Swollman# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST" 63186222Swollman# versus "AEST" etc.: 63286222Swollman# 63386222Swollman# I see the following points of dispute: 63486222Swollman# 63586222Swollman# * How important are unique time zone abbreviations? 63686222Swollman# 63786222Swollman# Here I tend to agree with the point (most recently made by Chris 63886222Swollman# Newman) that unique abbreviations should not be essential for proper 63986222Swollman# operation of software. We have other instances of ambiguity 64086222Swollman# (e.g. "IST" denoting both "Israel Standard Time" and "Indian 64186222Swollman# Standard Time"), and they are not likely to go away any time soon. 64286222Swollman# In the old days, some software mistakenly relied on unique 64386222Swollman# abbreviations, but this is becoming less true with time, and I don't 64486222Swollman# think it's that important to cater to such software these days. 64586222Swollman# 64686222Swollman# On the other hand, there is another motivation for unambiguous 64786222Swollman# abbreviations: it cuts down on human confusion. This is 64886222Swollman# particularly true for Australia, where "EST" can mean one thing for 64986222Swollman# time T and a different thing for time T plus 1 second. 65086222Swollman# 65186222Swollman# * Does the relevant legislation indicate which abbreviations should be used? 65286222Swollman# 65386222Swollman# Here I tend to think that things are a mess, just as they are in 65486222Swollman# many other countries. We Americans are currently disagreeing about 65586222Swollman# which abbreviation to use for the newly legislated Chamorro Standard 65686222Swollman# Time, for example. 65786222Swollman# 65886222Swollman# Personally, I would prefer to use common practice; I would like to 65986222Swollman# refer to legislation only for examples of common practice, or as a 66086222Swollman# tiebreaker. 66186222Swollman# 66286222Swollman# * Do Australians more often use "Eastern Daylight Time" or "Eastern 66386222Swollman# Summer Time"? Do they typically prefix the time zone names with 66486222Swollman# the word "Australian"? 66586222Swollman# 66686222Swollman# My own impression is that both "Daylight Time" and "Summer Time" are 66786222Swollman# common and are widely understood, but that "Summer Time" is more 66886222Swollman# popular; and that the leading "A" is also common but is omitted more 66986222Swollman# often than not. I just used AltaVista advanced search and got the 67086222Swollman# following count of page hits: 67186222Swollman# 67286222Swollman# 1,103 "Eastern Summer Time" AND domain:au 67386222Swollman# 971 "Australian Eastern Summer Time" AND domain:au 67486222Swollman# 613 "Eastern Daylight Time" AND domain:au 67586222Swollman# 127 "Australian Eastern Daylight Time" AND domain:au 67686222Swollman# 67786222Swollman# Here "Summer" seems quite a bit more popular than "Daylight", 67886222Swollman# particularly when we know the time zone is Australian and not US, 67986222Swollman# say. The "Australian" prefix seems to be popular for Eastern Summer 68086222Swollman# Time, but unpopular for Eastern Daylight Time. 68186222Swollman# 68286222Swollman# For abbreviations, tools like AltaVista are less useful because of 68386222Swollman# ambiguity. Many hits are not really time zones, unfortunately, and 68486222Swollman# many hits denote US time zones and not Australian ones. But here 68586222Swollman# are the hit counts anyway: 68686222Swollman# 68786222Swollman# 161,304 "EST" and domain:au 68886222Swollman# 25,156 "EDT" and domain:au 68986222Swollman# 18,263 "AEST" and domain:au 69086222Swollman# 10,416 "AEDT" and domain:au 69186222Swollman# 69286222Swollman# 14,538 "CST" and domain:au 69386222Swollman# 5,728 "CDT" and domain:au 69486222Swollman# 176 "ACST" and domain:au 69586222Swollman# 29 "ACDT" and domain:au 69686222Swollman# 69786222Swollman# 7,539 "WST" and domain:au 69886222Swollman# 68 "AWST" and domain:au 69986222Swollman# 70086222Swollman# This data suggest that Australians tend to omit the "A" prefix in 70186222Swollman# practice. The situation for "ST" versus "DT" is less clear, given 70286222Swollman# the ambiguities involved. 70386222Swollman# 70486222Swollman# * How do Australians feel about the abbreviations in the tz database? 70586222Swollman# 70686222Swollman# If you just count Australians on this list, I count 2 in favor and 3 70786222Swollman# against. One of the "against" votes (David Keegel) counseled delay, 70886222Swollman# saying that both AEST/AEDT and EST/EST are widely used and 70986222Swollman# understood in Australia. 71086222Swollman 71114343Swollman# From Paul Eggert (1995-12-19): 712158421Swollman# Shanks & Pottenger report 2:00 for all autumn changes in Australia and NZ. 713149514Swollman# Mark Prior writes that his newspaper 7149908Swollman# reports that NSW's fall 1995 change will occur at 2:00, 7159908Swollman# but Robert Elz says it's been 3:00 in Victoria since 1970 7169908Swollman# and perhaps the newspaper's `2:00' is referring to standard time. 71714343Swollman# For now we'll continue to assume 2:00s for changes since 1960. 7182742Swollman 719149514Swollman# From Eric Ulevik (1998-01-05): 72075267Swollman# 72143014Swollman# Here are some URLs to Australian time legislation.

Mapmakers are free to draw it as they please. 144258787Sru# Reputable mapmakers will simply ensure that every point of land appears on 144358787Sru# the correct side of the IDL, according to the date legally observed there. 144458787Sru# 144558787Sru# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and 144658787Sru# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL 144758787Sru# to the east side of the Phoenix and Line Islands), I suppose that most 144858787Sru# mapmakers redrew the IDL following the boundary of Kiribati. Even that line 144958787Sru# has a rather arbitrary nature. The straight-line boundaries between Pacific 145058787Sru# island nations that are shown on many maps are based on an international 1451153670Swollman# convention, but are not legally binding national borders.... The date is 145258787Sru# governed by the IDL; therefore, even on the high seas, there may be some 145358787Sru# places as late as fourteen hours later than UTC. And, since the IDL is not 145458787Sru# an international standard, there are some places on the high seas where the 145558787Sru# correct date is ambiguous. 1456149514Swollman 1457153670Swollman# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31): 1458153670Swollman# Before 1920, all ships kept local apparent time on the high seas by setting 1459153670Swollman# their clocks at night or at the morning sight so that, given the ship's 1460153670Swollman# speed and direction, it would be 12 o'clock when the Sun crossed the ship's 1461153670Swollman# meridian (12 o'clock = local apparent noon). During 1917, at the 1462153670Swollman# Anglo-French Conference on Time-keeping at Sea, it was recommended that all 1463153670Swollman# ships, both military and civilian, should adopt hourly standard time zones 1464153670Swollman# on the high seas. Whenever a ship was within the territorial waters of any 1465153670Swollman# nation it would use that nation's standard time. The captain was permitted 1466153670Swollman# to change his ship's clocks at a time of his choice following his ship's 1467153670Swollman# entry into another zone time--he often chose midnight. These zones were 1468153670Swollman# adopted by all major fleets between 1920 and 1925 but not by many 1469153670Swollman# independent merchant ships until World War II. 1470153670Swollman 1471149514Swollman# From Paul Eggert, using references suggested by Oscar van Vlijmen 1472149514Swollman# (2005-03-20): 1473149514Swollman# 1474149514Swollman# The American Practical Navigator (2002) 1475149514Swollman# <http://pollux.nss.nima.mil/pubs/pubs_j_apn_sections.html?rid=187> 1476149514Swollman# talks only about the 180-degree meridian with respect to ships in 1477149514Swollman# international waters; it ignores the international date line. 1478
