Australian time zones:

ACST – Australian Central Standard Time

Time zone offset: UTC + 9:30 hours

ACST is 9 hours and 30 minutes ahead of Coordinated Universal Time (UTC)

Note that some places observe daylight saving time/summer time during summer, and are therefore using ACDT instead in the summer. See below for details.

Time zone abbreviation: ACST

Full name is Australian Central Standard Time

Email time zone indicator: +0930

An email sent from someone in the ACST time zone will have the time zone listed as "+0930" in the headers of the email. (However, "+0930" does not have to be in ACST, as other time zones could have the same UTC offset).

For actual dates DST might be observed, look at the examples below
