I'm forwarding this message from Mark Jerkovic, who is not on the time zone mailing list. Those of you who are on the time zone list should direct replies appropriately. --ado From: Mark Jerkovic [mailto:mjerkovic@aconex.com] Sent: Thursday, November 01, 2007 7:24 PM To: tz@lecserver.nci.nih.gov Subject: Australian time zone names Hi, I would like to propose an amendment to the format of Australian timezones. Currently the format is EST for eastern states and WST for western states. This is incorrect. The Australian Government defines time zone names as follows: Time Zones There are three times zones in Australia - Eastern Australian Eastern Standard Time (AEST) is equal to Greenwich Mean Time plus 10 hours (GMT +10). AEST is followed in these regions: • New South Wales (except Broken Hill) • Victoria • Queensland • Tasmania • Australian Capital Territory Central Australian Central Standard Time (ACST) is equal to Greenwich Mean Time plus 9 ½ hours (GMT +9 ½). ACST is followed in these regions: • South Australia • Northern Territory • Broken Hill, NSW Western Australian Western Standard Time (AWST) is equal to Greenwich Mean Time plus 8 hours (GMT +8). AWST is followed in these regions: • Western Australia Daylight Saving Daylight saving time is observed by New South Wales, Victoria, South Australia, Tasmania, and the Australian Capital Territory from early to late October to the end of March. Western Australia began a three year trial of daylight saving on 3 December 2006. Queensland and the Northern Territory do not observe daylight savings. Where daylight saving is being observed: • AEST becomes Australian Eastern Daylight Time (AEDT), and clocks are advanced to GMT +11. • ACST becomes Australian Central Daylight Time (ACDT), and clocks are advanced to GMT +10 ½. • AWST becomes Australian Western Daylight Time (AWDT), and clocks are advanced to GMT +9. The link where this came from is http://www.australia.gov.au/Time_Zones Could these naming conventions be added to the timezone database? Thanks, Mark.
