Questions

How do I convert a cron expression from WAT to JST?

JST is currently 8 hours ahead of WAT. Add 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 WAT) becomes 0 17 * * 1-5 in JST.

What is the time difference between WAT and JST?

West Africa Time is UTC+1 and Japan Standard Time is UTC+9. Right now jST is currently 8 hours ahead of WAT.

Does daylight saving time affect WAT to JST cron conversion?

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

What is midnight WAT in JST cron?

Midnight in WAT (0 0 * * *) is 0 8 * * * in JST.
