Australian Central Daylight Time Zone - ACDT

Australian Central Daylight Time or ACDT has a UTC offset of +10:30. This means that the time zone is 10 and a half hours ahead of Coordinated Universal Time. The time zone is primarily observed by territories and states in Australia during the summer months when Daylight Saving is active. After Daylight Saving is over – during the winter – the affected territories switch to Australian Central Standard Time or ACST.

Australian Central Daylight Time is what is referred to as a non-standard half-hour time zone. This means there is a 30 minute difference in local time from the actual one-hour time zone interval you’d usually see if traditional time standards were used.
