Questions

How do I convert a cron expression from HST to ACST?

ACST is currently 20 hours 30 minutes ahead of HST. Add 20 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 HST) becomes 30 5 * * 2-6 in ACST.

What is the time difference between HST and ACST?

Hawaii Time is UTC-10 and Australian Central Time is UTC+9:30 / UTC+10:30. Right now aCST is currently 20 hours 30 minutes ahead of HST.

Does daylight saving time affect HST to ACST cron conversion?

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

What is midnight HST in ACST cron?
