Questions

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

KST and JST currently share the same offset. No change is needed. For example, 0 9 * * 1-5 (weekdays at 09:00 JST) becomes 0 9 * * 1-5 in KST.

What is the time difference between JST and KST?

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

Does daylight saving time affect JST to KST cron conversion?

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

What is midnight JST in KST cron?

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