Thanks for the response, Dave, but that was the first thing I checked.
What we were actually seeing is backups starting at, say 11am, for a
schedule that was supposed to last from 6pm to 8am.  It was happening
to enough users that I became convinced that there was no mistake.  Now
that you agree that this is not what is supposed to happen, I will try
easing the duration up again and listen for complaints.
