Questions

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

SAST is currently 6 hours behind CST. Subtract 6 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 CST) becomes 0 3 * * 1-5 in SAST.

What is the time difference between CST and SAST?

China Standard Time is UTC+8 and South Africa Standard Time is UTC+2. Right now sAST is currently 6 hours behind CST.

Does daylight saving time affect CST to SAST cron conversion?

Neither CST nor SAST observes daylight saving time, so the 6 hours difference stays the same all year.

What is midnight CST in SAST cron?

Midnight in CST (0 0 * * *) is 0 18 * * * in SAST, on the previous day.
