Questions

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

KST is currently 7 hours ahead of SAST. Add 7 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 SAST) becomes 0 16 * * 1-5 in KST.

What is the time difference between SAST and KST?

South Africa Standard Time is UTC+2 and Korea Standard Time is UTC+9. Right now kST is currently 7 hours ahead of SAST.

Does daylight saving time affect SAST to KST cron conversion?

Neither SAST nor KST observes daylight saving time, so the 7 hours difference stays the same all year.

What is midnight SAST in KST cron?

Midnight in SAST (0 0 * * *) is 0 7 * * * in KST.
