Generalized Time Zones in Australia
|Time Zone Abbreviation & Name||Offset||Current Time|
|ACT||Australian Central Time||UTC +9:30 / +10:30||Mon, 4:34:23 am|
|AET||Australian Eastern Time||UTC +10:00 / +11:00||Mon, 5:04:23 am|
Time zones in mainland Australia are often referred to by their generic name, without differentiating between standard time and Daylight Saving Time designations. For example, Australian Central Time (ACT) refers to both Australian Central Standard Time (ACST) and Australian Central Daylight Time (ACDT), depending on which is currently in use.
Note: Local time in these time zones changes when Daylight Saving Time begins and ends.
