We do this by overriding datetime.datetime with mock objects
that represent increasing system times.
Please note that it is *intended behavior that run_pending() does not
run missed jobs*. For example, if you've registered a job that
should run every minute and you only call run_pending() in one hour
increments then your job won't be run 60 times in between but
only once.
