Questions

How do I convert a cron expression from ACST to GMT?

GMT is currently 10 hours 30 minutes behind ACST. Subtract 10 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 ACST) becomes 30 22 * * 0-4 in GMT.

What is the time difference between ACST and GMT?

Australian Central Time is UTC+9:30 / UTC+10:30 and Greenwich Mean Time (UK) is UTC+0 / UTC+1. Right now gMT is currently 10 hours 30 minutes behind ACST.

Does daylight saving time affect ACST to GMT cron conversion?

ACST and GMT observe daylight saving time, so the difference between ACST (UTC+9:30 / UTC+10:30) and GMT (UTC+0 / UTC+1) changes during the year. Re-check your converted cron after each DST change.

What is midnight ACST in GMT cron?

Midnight in ACST (0 0 * * *) is 30 13 * * * in GMT, on the previous day.
