Defined at:

Filter to override scheduling an event.

Returning a non-null value will short-circuit adding the event to the cron array, causing the function to return the filtered value instead.

Both single events and recurring events are passed through this filter; single events have $event->schedule as false, whereas recurring events have this set to a recurrence from wp_get_schedules(). Recurring events also have the integer recurrence interval set as $event->interval.

For plugins replacing wp-cron, it is recommended you check for an identical event within ten minutes and apply the {@see 'schedule_event'} filter to check if another plugin has disallowed the event before scheduling.

Return true if the event was scheduled, false or a WP_Error if not.
