Questions

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

WAT is currently 8 hours behind JST. 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 JST) becomes 0 1 * * 1-5 in WAT.

What is the time difference between JST and WAT?

Japan Standard Time is UTC+9 and West Africa Time is UTC+1. Right now wAT is currently 8 hours behind JST.

Does daylight saving time affect JST to WAT cron conversion?

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

What is midnight JST in WAT cron?

Midnight in JST (0 0 * * *) is 0 16 * * * in WAT, on the previous day.
