 Review comment:
   I am still getting confused here. You might have already talked about this to @ashb but it would be good if you can clear my doubt.
   
   My confusion is the same that Ash mentioned in one of the comments, what is the difference between `schedulable_at` and `next_execution_date`?
   
   From the code will it not give the `schedulable_at=next_execution_date + schedule_interval` ?
