Questions

How do I convert a cron expression from BRT to HST?

HST is currently 7 hours behind BRT. Subtract 7 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 BRT) becomes 0 2 * * 1-5 in HST.

What is the time difference between BRT and HST?

Brasília Time is UTC-3 and Hawaii Time is UTC-10. Right now hST is currently 7 hours behind BRT.

Does daylight saving time affect BRT to HST cron conversion?

Neither BRT nor HST observes daylight saving time, so the 7 hours difference stays the same all year.

What is midnight BRT in HST cron?

Midnight in BRT (0 0 * * *) is 0 17 * * * in HST, on the previous day.
