How is it possible, or what format do I need to be able to subract time
across days. Example, would be if I'm trying to see how long it took to get
a response to a problem or breakdown. Say the request came in at 11:30PM and
the action began at 12:15AM, 45 minutes later. However, if you simply
subtract the two cells, it just puts a whole line of ##############. I
cannot figure out how to do this.

Thanks,
