Below we should see the following:
- On Jan 31 only e2 is executed, because we started later than
e1 should have been executed. Offset of e2 is 0 because of
the late start, not 1.
- The next execution is on Feb 28 (last day of Feb). Both events
are executed in their times, offsets are -1 and 1.
- The next time is Mar 31. Because the time of event
execution was skipped over, events are executed right away,
offsets are 2 and 2.
- The next time is Apr 30. Events are again executed in their
appointed times, offsets are -1 and 1.
