How to use it
Use it for hourly rollups or cleanup jobs that do not need minute-level freshness.
Change the first field to 30 to run at half past every hour.
Always confirm the scheduler time zone. A daily or weekly cron can move relative to UTC when the local zone enters or leaves daylight saving time.
