Bill Thurmes, Miyota Development Center of America

Add two times, in h:mm:ss format, together

Sample Input:
AddTimes ( "28:35" ; "35:47" )
AddTimes ( "28:13" ; "31:30" )
Sample Output:

 Then copy & paste into FileMaker Advanced's Edit Custom Function window.


Time2 will be added to Time1
Entry format should be h:mm:ss, or mm:ss, or ss
Result will be in same format, dropping unneeded info from left.
If you want an h:mm:ss output, just drop the lines after t = Time (... and output t.
Primarily useful if the time format is/might be mm:ss
It now gives a negative answer if Time1 is before Time2

Note: these functions are not guaranteed or supported by Please contact the individual developer with any questions or problems.

This is my Custom Function and I want to edit it


Filemaker can add and subtract times natively.

Thanks. I had needed something to add text that was in a mm:ss format, which Filemaker's native time addition doesn't deal with well. I've changed the script to use Filemaker's native capabilities.
