 Pulp supports scheduling of tasks. Scheduled tasks will be dispatched shortly after their
 `next_dispatch` time, and be rescheduled one `dispatch_interval` after that, if the latter is
 set. By specifying the `dispatch_interval` as `time_delta(days=1)` you can expect the task

 therefore scheduled task dispatching will be missed if all workers are offline. After an outage
 window, overdue schedules will dispatch at most one task, but down to timing, they may be
