Australian time zones:

CST – Central Standard Time

Time zone offset: UTC + 9:30 hours

CST 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 CDT instead in the summer. See below for details.

Time zone abbreviations: CST, ACST

Full name is Central Standard Time
ACST – Australian Central Standard Time (Alternative - often used in international context to avoid confusion with CST/Central Standard Time in Northern America)

Email time zone indicator: +0930

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

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