Questions

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

CST is currently 18 hours ahead of HST. Add 18 hours to the hour field, and shift the day-of-week if the time crosses midnight. For example, 0 9 * * 1-5 (weekdays at 09:00 HST) becomes 0 3 * * 2-6 in CST.

What is the time difference between HST and CST?

Hawaii Time is UTC-10 and China Standard Time is UTC+8. Right now cST is currently 18 hours ahead of HST.

Does daylight saving time affect HST to CST cron conversion?

Neither HST nor CST observes daylight saving time, so the 18 hours difference stays the same all year.

What is midnight HST in CST cron?

Midnight in HST (0 0 * * *) is 0 18 * * * in CST.
