The globe is divided into Standard time zones and Local Standard Time is the time specified for each zone. This is usually done in terms of hours ahead or behind GMT. The LST zones in Australia are as follows:
AEST - Australian Eastern Standard Time (GMT +10) in Queensland, New South Wales, Victoria and Tasmania
ACST - Australian Central Standard Time (GMT +9.5) in Northern Territories and South Australia
AWST - Australian Western Standard Time (GMT +8) in Western Australia.

AEDT Daylight Saving Dates
At start of daylight saving period, move clock forward one hour at 2 am EST (Eastern Standard Time).
At end of daylight saving period, move clock back one hour at 2 am EST (Eastern Standard Time).
Experimentally in use between 2006 - 2009 and then abandoned.
Normally this is the same as Local Standard Time, but in periods of Daylight Saving an hour is added to the local clock, making Local Time an hour ahead of Local Standard Time (i.e. Local time = DST).
