Interesting, although I find it hard to believe that any self respecting Aussie would use Central Summer Time, since the normal name is Central Daylight Time, and I'd suspect that "Summer Time" would be considered a Pommie afectation. Most countries which use Summer instead of Daylight in TZ period abreviations seem to not use the lack of a letter, or an entirely different abbreviation for the winter time GMT, and BST, or IST CET, and CEST etc. but it's quite true that time zone period abbreviations can't in general be used to identify a particular time zone, even at a given period of time. Another complication being that such things tend to change with new governents, laws, and whims. A good list of abbreviations can be found at: http://www.timeanddate.com/library/abbreviations/timezones/ -- Rick DeNatale Blog: http://talklikeaduck.denhaven2.com/ Twitter: http://twitter.com/RickDeNatale WWR: http://www.workingwithrails.com/person/9021-rick-denatale LinkedIn: http://www.linkedin.com/in/rickdenatale --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
