Questions

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

ART is currently 12 hours behind KST. Subtract 12 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 21 * * 0-4 in ART.

What is the time difference between KST and ART?

Korea Standard Time is UTC+9 and Argentina Time is UTC-3. Right now aRT is currently 12 hours behind KST.

Does daylight saving time affect KST to ART cron conversion?

Neither KST nor ART observes daylight saving time, so the 12 hours difference stays the same all year.

What is midnight KST in ART cron?

Midnight in KST (0 0 * * *) is 0 12 * * * in ART, on the previous day.
