Questions

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

HST is currently 10 hours behind UTC. Subtract 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 UTC) becomes 0 23 * * 0-4 in HST.

What is the time difference between UTC and HST?

Coordinated Universal Time is UTC+0 and Hawaii Time is UTC-10. Right now hST is currently 10 hours behind UTC.

Does daylight saving time affect UTC to HST cron conversion?

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

What is midnight UTC in HST cron?

Midnight in UTC (0 0 * * *) is 0 14 * * * in HST, on the previous day.
