ACST is currently 10 hours 30 minutes ahead of GMT. Add 10 hours 30 minutes to the hour and minute field, and shift the day-of-week if the time crosses midnight. For example, 0 9 * * 1-5 (weekdays at 09:00 GMT) becomes 30 19 * * 1-5 in ACST.

What is the time difference between GMT and ACST?

Greenwich Mean Time (UK) is UTC+0 / UTC+1 and Australian Central Time is UTC+9:30 / UTC+10:30. Right now aCST is currently 10 hours 30 minutes ahead of GMT.

Does daylight saving time affect GMT to ACST cron conversion?

GMT and ACST observe daylight saving time, so the difference between GMT (UTC+0 / UTC+1) and ACST (UTC+9:30 / UTC+10:30) changes during the year. Re-check your converted cron after each DST change.
