Time/Date Calculations
Use this screen to calculate the dif-
ference between two Time and/or
Date values. The result is returned
in two formats:
1. Standard Difference
in Days,
Hours, Minutes and Seconds.
2.
Unit Difference

following units: year, month, day,
hour, minute or second.
When you open this screen, both
dates will be set to today and both
times will be set to current time.
