Questions

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

GST is currently 5 hours behind JST. Subtract 5 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 JST) becomes 0 4 * * 1-5 in GST.

What is the time difference between JST and GST?

Japan Standard Time is UTC+9 and Gulf Standard Time is UTC+4. Right now gST is currently 5 hours behind JST.

Does daylight saving time affect JST to GST cron conversion?

Neither JST nor GST observes daylight saving time, so the 5 hours difference stays the same all year.

What is midnight JST in GST cron?

Midnight in JST (0 0 * * *) is 0 19 * * * in GST, on the previous day.
