ooo-cron provides a simple multiserver-coordinate cron service. Coordination takes place via a shared database table, which is used to ensure that only one of the various servers executes a cron job for a given occurrence.
Jobs can be scheduled to run on a given period, or at a specific time of day.
CronLogic class for details.
