Now by a happy coincidence, `summer' 527# and `standard' happen to start with the same letter; hence, the 528# abbreviation does _not_ change... 529# The legislation does not actually define abbreviations, at least 530# in this State, but the abbreviation is just commonly taken to be the 531# initials of the phrase, and the legislation here uniformly uses 532# the phrase `summer time' and does not use the phrase `daylight 533# time'. 534# Announcers on the Commonwealth radio network, the ABC (for Australian 535# Broadcasting Commission), use the phrases `Eastern Standard Time' 536# or `Eastern Summer Time'. (Note, though, that as I say in the 537# current australasia file, there is really no such thing.) Announcers 538# on its overseas service, Radio Australia, use the same phrases 539# prefixed by the word `Australian' when referring to local times; 540# time announcements on that service, naturally enough, are made in UTC. 541 542# From Arthur David Olson (1992-03-08): 543# Given the above, what's chosen for year-round use is: 544# CST for any place operating at a GMTOFF of 9:30 545# WST for any place operating at a GMTOFF of 8:00 546# EST for any place operating at a GMTOFF of 10:00 547 548# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST" 549# versus "AEST" etc.: 550# 551# I see the following points of dispute: 552# 553# * How important are unique time zone abbreviations? 554# 555# Here I tend to agree with the point (most recently made by Chris 556# Newman) that unique abbreviations should not be essential for proper 557# operation of software. We have other instances of ambiguity 558# (e.g. "IST" denoting both "Israel Standard Time" and "Indian 559# Standard Time"), and they are not likely to go away any time soon. 560# In the old days, some software mistakenly relied on unique 561# abbreviations, but this is becoming less true with time, and I don't 562# think it's that important to cater to such software these days. 563# 564# On the other hand, there is another motivation for unambiguous 565# abbreviations: it cuts down on human confusion. This is 566# particularly true for Australia, where "EST" can mean one thing for 567# time T and a different thing for time T plus 1 second. 568# 569# * Does the relevant legislation indicate which abbreviations should be used? 570# 571# Here I tend to think that things are a mess, just as they are in 572# many other countries. We Americans are currently disagreeing about 573# which abbreviation to use for the newly legislated Chamorro Standard 574# Time, for example. 575# 576# Personally, I would prefer to use common practice; I would like to 577# refer to legislation only for examples of common practice, or as a 578# tiebreaker. 579# 580# * Do Australians more often use "Eastern Daylight Time" or "Eastern 581# Summer Time"? Do they typically prefix the time zone names with 582# the word "Australian"? 583# 584# My own impression is that both "Daylight Time" and "Summer Time" are 585# common and are widely understood, but that "Summer Time" is more 586# popular; and that the leading "A" is also common but is omitted more 587# often than not. I just used AltaVista advanced search and got the 588# following count of page hits: 589# 590# 1,103 "Eastern Summer Time" AND domain:au 591# 971 "Australian Eastern Summer Time" AND domain:au 592# 613 "Eastern Daylight Time" AND domain:au 593# 127 "Australian Eastern Daylight Time" AND domain:au 594# 595# Here "Summer" seems quite a bit more popular than "Daylight", 596# particularly when we know the time zone is Australian and not US, 597# say. The "Australian" prefix seems to be popular for Eastern Summer 598# Time, but unpopular for Eastern Daylight Time. 599# 600# For abbreviations, tools like AltaVista are less useful because of 601# ambiguity. Many hits are not really time zones, unfortunately, and 602# many hits denote US time zones and not Australian ones. But here 603# are the hit counts anyway: 604# 605# 161,304 "EST" and domain:au 606# 25,156 "EDT" and domain:au 607# 18,263 "AEST" and domain:au 608# 10,416 "AEDT" and domain:au 609# 610# 14,538 "CST" and domain:au 611# 5,728 "CDT" and domain:au 612# 176 "ACST" and domain:au 613# 29 "ACDT" and domain:au 614# 615# 7,539 "WST" and domain:au 616# 68 "AWST" and domain:au 617# 618# This data suggest that Australians tend to omit the "A" prefix in 619# practice. The situation for "ST" versus "DT" is less clear, given 620# the ambiguities involved. 621# 622# * How do Australians feel about the abbreviations in the tz database? 623# 624# If you just count Australians on this list, I count 2 in favor and 3 625# against. One of the "against" votes (David Keegel) counseled delay, 626# saying that both AEST/AEDT and EST/EST are widely used and 627# understood in Australia. 628 629# From Paul Eggert (1995-12-19): 630# Shanks reports 2:00 for all autumn changes in Australia and New Zealand. 631# Mark Prior <mrp@itd.adelaide.edu.au> writes that his newspaper 632# reports that NSW's fall 1995 change will occur at 2:00, 633# but Robert Elz says it's been 3:00 in Victoria since 1970 634# and perhaps the newspaper's `2:00' is referring to standard time. 635# For now we'll continue to assume 2:00s for changes since 1960. 636 637# From Eric Ulevik <eau@zip.com.au> (1998-01-05): 638# 639# Here are some URLs to Australian time legislation.

We have other instances of ambiguity 556# (e.g. "IST" denoting both "Israel Standard Time" and "Indian 557# Standard Time"), and they are not likely to go away any time soon. 558# In the old days, some software mistakenly relied on unique 559# abbreviations, but this is becoming less true with time, and I don't 560# think it's that important to cater to such software these days. 561# 562# On the other hand, there is another motivation for unambiguous 563# abbreviations: it cuts down on human confusion. This is 564# particularly true for Australia, where "EST" can mean one thing for 565# time T and a different thing for time T plus 1 second. 566# 567# * Does the relevant legislation indicate which abbreviations should be used? 568# 569# Here I tend to think that things are a mess, just as they are in 570# many other countries. We Americans are currently disagreeing about 571# which abbreviation to use for the newly legislated Chamorro Standard 572# Time, for example. 573# 574# Personally, I would prefer to use common practice; I would like to 575# refer to legislation only for examples of common practice, or as a 576# tiebreaker. 577# 578# * Do Australians more often use "Eastern Daylight Time" or "Eastern 579# Summer Time"? Do they typically prefix the time zone names with 580# the word "Australian"? 581# 582# My own impression is that both "Daylight Time" and "Summer Time" are 583# common and are widely understood, but that "Summer Time" is more 584# popular; and that the leading "A" is also common but is omitted more 585# often than not. I just used AltaVista advanced search and got the 586# following count of page hits: 587# 588# 1,103 "Eastern Summer Time" AND domain:au 589# 971 "Australian Eastern Summer Time" AND domain:au 590# 613 "Eastern Daylight Time" AND domain:au 591# 127 "Australian Eastern Daylight Time" AND domain:au 592# 593# Here "Summer" seems quite a bit more popular than "Daylight", 594# particularly when we know the time zone is Australian and not US, 595# say. The "Australian" prefix seems to be popular for Eastern Summer 596# Time, but unpopular for Eastern Daylight Time. 597# 598# For abbreviations, tools like AltaVista are less useful because of 599# ambiguity. Many hits are not really time zones, unfortunately, and 600# many hits denote US time zones and not Australian ones. But here 601# are the hit counts anyway: 602# 603# 161,304 "EST" and domain:au 604# 25,156 "EDT" and domain:au 605# 18,263 "AEST" and domain:au 606# 10,416 "AEDT" and domain:au 607# 608# 14,538 "CST" and domain:au 609# 5,728 "CDT" and domain:au 610# 176 "ACST" and domain:au 611# 29 "ACDT" and domain:au 612# 613# 7,539 "WST" and domain:au 614# 68 "AWST" and domain:au 615# 616# This data suggest that Australians tend to omit the "A" prefix in 617# practice. The situation for "ST" versus "DT" is less clear, given 618# the ambiguities involved. 619# 620# * How do Australians feel about the abbreviations in the tz database? 621# 622# If you just count Australians on this list, I count 2 in favor and 3 623# against. One of the "against" votes (David Keegel) counseled delay, 624# saying that both AEST/AEDT and EST/EST are widely used and 625# understood in Australia. 626 627# From Paul Eggert (1995-12-19): 628# Shanks reports 2:00 for all autumn changes in Australia and New Zealand. 629# Mark Prior <mrp@itd.adelaide.edu.au> writes that his newspaper 630# reports that NSW's fall 1995 change will occur at 2:00, 631# but Robert Elz says it's been 3:00 in Victoria since 1970 632# and perhaps the newspaper's `2:00' is referring to standard time. 633# For now we'll continue to assume 2:00s for changes since 1960. 634 635# From Eric Ulevik <eau@zip.com.au> (1998-01-05): 636# 637# Here are some URLs to Australian time legislation.
