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.
