Questions

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

What is the time difference between KST and JST?

Korea Standard Time is UTC+9 and Japan Standard Time is UTC+9. Right now jST and KST currently share the same offset.

Does daylight saving time affect KST to JST cron conversion?

Neither KST nor JST observes daylight saving time, so the 0 hours difference stays the same all year.

Midnight in KST (0 0 * * *) is 0 0 * * * in JST.
