Questions

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

HST is currently 18 hours behind CST. Subtract 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 CST) becomes 0 15 * * 0-4 in HST.

What is the time difference between CST and HST?

China Standard Time is UTC+8 and Hawaii Time is UTC-10. Right now hST is currently 18 hours behind CST.

Does daylight saving time affect CST to HST cron conversion?

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

What is midnight CST in HST cron?

Midnight in CST (0 0 * * *) is 0 6 * * * in HST, on the previous day.
