Questions

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

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

What is the time difference between SGT and SAST?

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

Does daylight saving time affect SGT to SAST cron conversion?

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

What is midnight SGT in SAST cron?

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