There are three different timezones in Australia, and in two of these some areas observe Daylight Savings Time and some do not, and in some areas DST starts earlier than others, so you need a minimum of 6 options. These options, using the standard nomenclature are: ------------- 1. Australia/Perth or Australia/Western Australia GMT+8 no DST 2. Australia/Darwin or Australia/Northern Territory GMT+9:30 no DST 3. Australia/Adelaide or Australia/South Australia GMT+9:30 DST Oct-Mar 4. Australia/Brisbane or Australia/Queensland GMT+10 no DST 5. Australia/Sydney or Australia/NSW GMT+10 DST Oct-Mar Australia/Melbourne or Australia/Victoria GMT+10 DST Oct-Mar (same as Australia/Sydney) Australia/Canberra or Australia/ACT GMT+10 DST Oct-Mar (same as Australia/Sydney) 6. Australia/Hobart or Australia/Tasmania GMT+10 DST Oct-Mar (but earlier start/later finish than previous three) --------- Australia/Sydney vs Australia/Melbourne vs Australia/Canberra is like US/Los Angeles vs US/San Francisco - just parochial naming preferences but same timezone. Note that Darwin and Adelaide have timezone which is a half-hour one - unusual, but correct. Also, can you please make sure that GMT/UTC is selectable as an option. Cheers Frank (who lives in one of the half-hour timezones)
