Questions

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

SGT 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 SGT.

What is the time difference between HST and SGT?

Hawaii Time is UTC-10 and Singapore Time is UTC+8. Right now sGT is currently 18 hours ahead of HST.

Does daylight saving time affect HST to SGT cron conversion?

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

What is midnight HST in SGT cron?

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