Things to watch out for in Google Cloud Scheduler
- Cloud Scheduler uses unix-cron, so */15 runs every 15 minutes at :00, :15, :30 and :45.
- Weekdays are 0-6 or SUN-SAT, and 7 is also accepted as Sunday.
- Cloud Scheduler takes any tz database zone (default UTC) and runs on wall-clock time, so daylight saving can make jobs run or not run unexpectedly. Google recommends UTC to avoid that.
The common mistake with this schedule
The last run is 17:45, not 17:00, because the hour range is 9-17 and the minute step still fires inside hour 17.
