Questions

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

SAST is currently 3 hours 30 minutes behind IST. Subtract 3 hours 30 minutes to the hour and minute field, and shift the day-of-week if the time crosses midnight. For example, 0 9 * * 1-5 (weekdays at 09:00 IST) becomes 30 5 * * 1-5 in SAST.

What is the time difference between IST and SAST?

India Standard Time is UTC+5:30 and South Africa Standard Time is UTC+2. Right now sAST is currently 3 hours 30 minutes behind IST.

Does daylight saving time affect IST to SAST cron conversion?

Neither IST nor SAST observes daylight saving time, so the 3 hours 30 minutes difference stays the same all year.

What is midnight IST in SAST cron?

Midnight in IST (0 0 * * *) is 30 20 * * * in SAST, on the previous day.
