If you have 2 time/date fields, you can simply subtract them. The result is the time difference in seconds. To get the difference in minutes, just divide the result by 60. If you have a situation that is not that simple, I think you should provide more info. BTW, the Designer help file does a decent job explaining time-date usage.
