Acrobat — Calculate time differences in a worksheet

With this script you can automatically calculate the time difference between a starting hour and an ending one. Sum up all times to a final piece.

In many timesheet-style PDF files you want to have a calculation of the time difference between a starting hour and an ending one. Something like when a worker checks in and then out. With this script you can automatically create the script to calculate that difference. There's also an option to sum up all times to a final piece.

This script can now also be used to total an entire column of time expressions to a single result field.
You can now use the script for either 24-hour or 12-hour time notations.You can now also select whether to show the results in decimal notation (so 2 hours and 30 minutes will show as "2.5") or in time notation (so 2 hours and 30 minutes will show as "2:30").
(19/06/2014) : It's no longer necessary to have the fields named with a number starting from 1. You can specify any starting index number (the default is still 1, though).

For example, this is the form we have:

We then run the script and get this window, into which we enter the names of the fields:

The script then runs and applies the calculation scripts:

And the final result is this (the total field is at the bottom-left):

How it works

  • Select your time fields
  • Select your time format
  • Calculate time differences!

I've been working with Gilad for almost 7 years on an evolving project that relies on lengthy complicated scripts. The turnaround times, pricing and accuracy are excellent. His depth of knowledge has been extremely helpful in helping define issues and offering options to accomplish the tasks. The add on scripts have been essential to maintaining and updating our existing documents as well. I highly recommend his services and products.

We first started working with Gilad back in 2015. I found him online in looking through different forum sites and realized he is an expert in Adobe and creating java scripts. I started with a small project and quickly realized he was an asset to have as a resource! Gilad has completed over 50 different projects for me. Each project has been completed on-time and he has been extremely easy to communicate with and his coding has always been accurate! I highly recommend Gilad and his team!

Gilad exceeded my expectations with nine different projects in which I sought his developer expertise.  He looks at your concept and suggests ways to make it more efficient.   Gilad sees additions or modifications you never considered and which ultimately prove invaluable.  If your concept has shortcomings, Gilad takes the time to explain them and then work with you to correct or replace them.  I wholeheartedly and unequivocally endorse Gilad as an expert developer.
