Questions

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

SAST is currently 2 hours behind GST. Subtract 2 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 GST) becomes 0 7 * * 1-5 in SAST.

What is the time difference between GST and SAST?

Gulf Standard Time is UTC+4 and South Africa Standard Time is UTC+2. Right now sAST is currently 2 hours behind GST.

Does daylight saving time affect GST to SAST cron conversion?

Neither GST nor SAST observes daylight saving time, so the 2 hours difference stays the same all year.

What is midnight GST in SAST cron?

Midnight in GST (0 0 * * *) is 0 22 * * * in SAST, on the previous day.
