Questions

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

HST is currently 14 hours behind GST. Subtract 14 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 GST) becomes 0 19 * * 0-4 in HST.

What is the time difference between GST and HST?

Gulf Standard Time is UTC+4 and Hawaii Time is UTC-10. Right now hST is currently 14 hours behind GST.

Does daylight saving time affect GST to HST cron conversion?

Neither GST nor HST observes daylight saving time, so the 14 hours difference stays the same all year.

What is midnight GST in HST cron?

Midnight in GST (0 0 * * *) is 0 10 * * * in HST, on the previous day.
