Questions

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

UTC 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 UTC.

What is the time difference between HST and UTC?

Hawaii Time is UTC-10 and Coordinated Universal Time is UTC+0. Right now uTC is currently 10 hours ahead of HST.

Does daylight saving time affect HST to UTC cron conversion?

Neither HST nor UTC observes daylight saving time, so the 10 hours difference stays the same all year.

What is midnight HST in UTC cron?

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