Add/Subtract Time

Calculate a time by adding or subtracting hours, minutes, and/or seconds to an existing time. The variables containing the existing time parameters will be overwritten by the result of the calculation.

  • The existing time must be stored in variables.

  • The hours, minutes, and/or seconds to be added to or subtracted from the existing time can be entered manually or copied from values stored in variables.

To learn more about properly formatting these variables, see A NOTE ABOUT FORMATTING.

  1. For the existing time: Enter the names of the variables in which each of the individual date parameters is stored.

  2. Enter the number of hours/minutes/seconds you would like to add to or subtract from the existing time.

    • To subtract hours/minutes/seconds, enter the values as negative. (To subtract using variables, the values stored in the variables must be negative.)

  3. Instruct the wizard how to handle any errors encountered. Read more about error handling.
