Questions

How do I convert a cron expression from AST to ART?

ART is currently 1 hour ahead of AST. Add 1 hour 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 AST) becomes 0 10 * * 1-5 in ART.

What is the time difference between AST and ART?

Atlantic Time is UTC-4 / UTC-3 and Argentina Time is UTC-3. Right now aRT is currently 1 hour ahead of AST.

Does daylight saving time affect AST to ART cron conversion?

AST observes daylight saving time, so the difference between AST (UTC-4 / UTC-3) and ART (UTC-3) changes during the year. Re-check your converted cron after each DST change.

What is midnight AST in ART cron?

Midnight in AST (0 0 * * *) is 0 1 * * * in ART.
