Why use this schedule
Twelve runs a day, at even hours (00:00, 02:00, 04:00 and so on). It halves the load of an hourly job while still catching changes within a couple of hours.
- Pulling analytics exports
- Rebalancing a recommendation cache
- Checking certificate expiry

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.
- Pick the time zone explicitly (the default is UTC). Cloud Scheduler runs on wall-clock time, so a local zone can make jobs run or skip around daylight saving changes.
- 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 step restarts at midnight, so */2 always means the even hours. If you need odd hours use 1-23/2.
