Questions

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

UTC is currently 8 hours behind HKT. Subtract 8 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 HKT) becomes 0 1 * * 1-5 in UTC.

What is the time difference between HKT and UTC?

Hong Kong Time is UTC+8 and Coordinated Universal Time is UTC+0. Right now uTC is currently 8 hours behind HKT.

Does daylight saving time affect HKT to UTC cron conversion?

Neither HKT nor UTC observes daylight saving time, so the 8 hours difference stays the same all year.

What is midnight HKT in UTC cron?

Midnight in HKT (0 0 * * *) is 0 16 * * * in UTC, on the previous day.
