Hi, Mark -- Replying to your "tz" list posting:
Using the Australia/Melbourne zone, it seems to imply that the format of the zone is EST regardless whether I am in day light savings or not.
My understanding has always been that the only truly official, legally blessed abbreviations for Australian time zones are EST, CST, and WST -- without any caring for confusion between summer (daylight saving) and non-summer time, and also without regard for confusion with similarly named and abbreviated time zones in North America. The abbreviations A{E,C,W}{S,D}T have been widely used on the Internet for many years, but the time zone gurus have been reluctant to use them because they've never been truly "official" as far as anyone knew. If reliable sources can be found showing that these abbreviations are now official throughout Australia, I imagine the keepers of the tz data would be more than delighted to update the database accordingly. However, I suspect people would prefer something more authoritative than a single web page (even if that page is on a government web site) -- hence the suggestion to go look up the current state of the relevant legislation for each Australian state/territory. -- Rich Wales === Palo Alto, CA, USA === richw@richw.org http://www.richw.org === http://en.wikipedia.org/wiki/User:Richwales
