Questions

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

ICT is currently 11 hours ahead of AST. Add 11 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 AST) becomes 0 20 * * 1-5 in ICT.

What is the time difference between AST and ICT?

Atlantic Time is UTC-4 / UTC-3 and Indochina Time is UTC+7. Right now iCT is currently 11 hours ahead of AST.

Does daylight saving time affect AST to ICT cron conversion?

AST observes daylight saving time, so the difference between AST (UTC-4 / UTC-3) and ICT (UTC+7) changes during the year. Re-check your converted cron after each DST change.

What is midnight AST in ICT cron?

Midnight in AST (0 0 * * *) is 0 11 * * * in ICT.
