Questions

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

JST is currently 5 hours ahead of GST. Add 5 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 GST) becomes 0 14 * * 1-5 in JST.

What is the time difference between GST and JST?

Gulf Standard Time is UTC+4 and Japan Standard Time is UTC+9. Right now jST is currently 5 hours ahead of GST.

Does daylight saving time affect GST to JST cron conversion?

Neither GST nor JST observes daylight saving time, so the 5 hours difference stays the same all year.

What is midnight GST in JST cron?

Midnight in GST (0 0 * * *) is 0 5 * * * in JST.
