Create a profile using the profiler just as you would before. Instead of
defining the number of 'periods per hour' just define the duration of each
period '20 minutes' or '4 hours'. The behavior of the profiler should be
exactly the same.
All of the unit and integration tests have been updated to reflect this
change and should pass. The integration test itself uses a '5 second' profile
period.
