Take an aicraft's Actual time of Departure (ATD) and subtract it from the Scheduled Departure Time (SDT) to display the Actual Delay in minutes.
Flight TA570 SDT 23:50 (time entered manually)
Actual Departure Time 00:22 (time entered manually)
Delay = 32 minutes (calculated by the script)
I know it's a simple task...but I am new using this thing and subtraction is not among the built-in Acrobat calculations.
Thanks for your time and help!!
