I have a VFP table with a start time and an end time. I report the start and end times in a Crystal Report detail line. What is the best way to compute the time interval (delta time) detail line, the difference between the start time and end time using Crystal Reports to do the computation?

My start time is defined as Character 8 for example 11:11:11
My end time is defined as Character 8 for example 12:12:12
This time interval would be 01:01:01.

Can I compute this with a one line formula in Crystal Reports? If so, what would it look like?

I know how to do it with many, many lines, but there must be a neater way to accomplish the same thing. Thanks so much.
