### Calculate and format an elapsed time value in Access

Question: In Access 2003/XP/2000/97, how do I format a time on a report so it appears as elapsed hours and minutes?
For example, 27 hours and 31 minutes appears as 27:31. I can do this for values up to 24 hours. But for anything over 24 hours, the full day(s) are dropped off.
