Elapsed Time calculations

[Hypoxic29028]

I am trying to get a simple time calculation to work on my PDF form. I am just wanting to created a time difference between and estimated amout of time (i.e. 1:45) and the actual time (i.e. 2:03)...  The result should simply display :18. I am not getting any of the simple formulas to work.

Thanks

I think that a similar inquiry was answered recently by Adobe Most Valuable Participant(MVP)  try67 in the following thread: https://community.adobe.com/t5/acrobat/add-1-min-to-time-field-with-hh-mm-format/m-p/11592660?page=1...

You'll need to use a JavaScript script to be able to calculate that difference between hours, minutes, and/or  seconds.
