Some of them may be but consider ... http://www.outback-australia-travel-secrets.com/australia-time-zones.html (for example) ... Sydney Australia Time Zone: UTC/GMT +10 hours (Eastern Standard Time EST) While that "EST" might perhaps come from our data, someone clearly wrote it as "Eastern Standard Time" by hand - that string isn't in the (compiled) data anywhere. | This also isn't just one site. This is the page that | has been specifically set up to state what the timezones of Australia | are. Yes, just like the one I quoted above, both are aimed at non-Australians (tourists, others wanting to know what time it is in Aust, etc). And both are equally authoritative (zero) - the Commonwealth govt has no authority over time (or what it is called) anywhere in Aust other than ACT, and Northern Territory. What's more, the page that quotes "AEST" and "AEDT" as the zones that apply in Victoria, also gives a link to "more information on daylight saving in Victoria", if you follow that, you find that (among other things) it says ... "Victoria's period of daylight saving will start at 2:00am on Sunday 7 October 2012. At 2:00am standard time (Eastern Standard Time) move clocks forward one hour to 3:00am summer time." Note "Eastern Standard Time" (not Australian Eastern Standard Time) and "to 3:00am summer time" (not to 3amm daylight saving time, and no "Australian" in that either). And this is a Vic Govt website, which is the govt that is responsible for defining the time in Victoria. Ref: http://www.vic.gov.au/daylight-saving-in-victoria.html You should also look at http://www.aph.gov.au/About_Parliament/Parliamentary_Departments/Parliamenta... (sorry about the long line) which is Research Paper no. 10 2009-10 Greg Baker Statistics and Mapping Section 19 November 2009 (I think this is "...Section of the Parliamentary Library" but I am not sure of thyat). It says, in part, ... Australia has three time zones. These are called Eastern Standard Time (EST), Central Standard Time (CST), and Western Standard Time (WST) which is sometimes called Western Australian Time. These zones are sometimes referred to as AEST, ACST and AWST respectively where the prefix refers to Australia. These time zones were set up by colonial legislatures in the mid to late 1890s.[6] EST is 10 hours ahead of UTC. In winter it applies to New South Wales, except in Broken Hill[7] which is on CST; Victoria; Queensland; Tasmania; and the Australian Capital Territory. Lord Howe Island is administratively part of New South Wales, but has standard time 10 hours 30 minutes ahead of UTC.[8] CST is 9 hours 30 minutes ahead of UTC. CST applies throughout South Australia, the Northern Territory and Broken Hill in New South Wales.[9] WST is 8 hours ahead of UTC and applies throughout Western Australia. Note the "sometimes referred to" where it refers to AEST (etc), and that it both gives, and internally uses, just "EST" (etc) as the proper abbreviation. There's a lot of useful information in that report (lots of historical info) and it looks to be well researched, it is not (and does not claim to be) authoritative for anything however (and I'm not saying it should be used that way.) | > Yes, official statements from national and state government departments | > would be useful. | Although I'm certainly making an attempt at this, For Qld, I think you'll be able to find (at least extracts from) the Standard Time Act, 1894, on line (just do a web search). From what I can tell, it still applies, essentially unammended. Note no typo, that's 1894 - pre federation, there was no "Australia" then, so it would be astounding if the official name for the timezone were "Australian" anything. In fact, from what I can determine, there is no real name in Qld, just "standard time", which is not surprising for the period. This is why I requested that you get some pointer to authority for whatever opinion you get, so we don't end up just taking some random minor bureaucrat's opinion as being blessed by some Govt authority. | If there are people in other states For NSW & ACT the statutes are also available, neither refer to "Australian" in the names (aside from the "A" in ACT), though from what I can see, neither refer to "Eastern" either, "New South Wales Standard Time" and "ACT Standard Time" appear to be what they use. Vic & Tas used to have legislation online, but it seems to be no longer available (unless you want to pay for it, the Summer Time Act 1972, Vic, is available for $3.90 if you want to acquire it). It used to say "Eastern Standard Time" and "Eastern Summer Time" and I doubt it has been changed (but feel free to acquire a copy, or go visit a law library and examine it there). I haven't looked for SA or WA (for the brief period Summer Time applied in WA). kre
