Questions

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

GST is currently 5 hours behind KST. Subtract 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 KST) becomes 0 4 * * 1-5 in GST.

What is the time difference between KST and GST?

Korea Standard Time is UTC+9 and Gulf Standard Time is UTC+4. Right now gST is currently 5 hours behind KST.

Does daylight saving time affect KST to GST cron conversion?

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

What is midnight KST in GST cron?

Midnight in KST (0 0 * * *) is 0 19 * * * in GST, on the previous day.
