Questions

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

GMT is currently 10 hours ahead of HST. Add 10 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 19 * * 1-5 in GMT.

What is the time difference between HST and GMT?

Hawaii Time is UTC-10 and Greenwich Mean Time (UK) is UTC+0 / UTC+1. Right now gMT is currently 10 hours ahead of HST.

Does daylight saving time affect HST to GMT cron conversion?

GMT observes daylight saving time, so the difference between HST (UTC-10) and GMT (UTC+0 / UTC+1) changes during the year. Re-check your converted cron after each DST change.

What is midnight HST in GMT cron?

Midnight in HST (0 0 * * *) is 0 10 * * * in GMT.
