ACST is currently 1 hour 30 minutes ahead of KST. Add 1 hour 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 KST) becomes 30 10 * * 1-5 in ACST.

What is the time difference between KST and ACST?

Does daylight saving time affect KST to ACST cron conversion?
