Database Cleaner can also list and show you all the cron jobs on your server. Cron jobs are entries in your database that WordPress checks against their scheduled values in order to run the code associated with each job at the appropriate time.

Database Cleaner itself uses cron jobs—such as the Nyao Sweeper—to clean your database at regular intervals.

You can view, delete, and inspect the schedule of each cron job, including when it is next scheduled to run.
