Australian Central Time (ACT) or the Australian Central Time Zone. This can add a bit of confusion as the term Australian Central Time does not differentiate between standard time and Daylight Saving Time, so Australian Central Time switches between ACST and ACDT in areas that use DST during part of the year.

Australia has two generic time zones that include both standard and daylight time: Australian Eastern Time (AET) and Australian Central Time (ACT). The country has a complex set of time zones, some of which have an unusual UTC offset.
