 * We have a file uploaded every 15 minutes at :00, :15, :30 and :45. I would like
   to run the Cron 5 minutes after every upload: at :05, :20, :35 and :50.
 * Is it possible to schedule this process as such?
 * Thank you,
   Lloyd.

 * You can do this by scheduling an event with:
    - A recurrence of every 15 minutes
    - A next run time of whenever the next :05, :20, :35, or :50 time is
 * However! It’s likely that these events won’t continue to fire at the expected
   times as the cron event runner in WordPress doesn’t guarantee when an event will
   run, and you’ll see some drift in the start time. For example if your site gets
   little traffic then the events can begin to run late and subsequent events will
   get scheduled 15 minutes after the late running one, and so on as late running
   events compound.
 * I’ve written about this here: [https://github.com/johnbillion/wp-crontrol/wiki/Cron-events-that-have-missed-their-schedule](https://github.com/johnbillion/wp-crontrol/wiki/Cron-events-that-have-missed-their-schedule)
 * Cavalcade (linked on that page) is your best bet to avoid this but requires you
   set up some additional infrastructure.
