Calculating times in pdf

[RI SFD5F8B]

Hello. I'm hoping someone can help me out. I am trying to make a pdf document which will calculate flight time by entering in departure and arrival times. The times will be entered in military time format. The times may also cross over midnight ( take off at 2300 and land at 0100). Finally we need the output to be calculate in decimals to a tenth of a minute (01-06 is a .1, 07-12 a .2 etc). 

E.g.- Takeoff at 2235 and land at 0115. Flight time should equal 2.7

Can the total time exceed 24 hours?

[RI SFD5F8B]

No it will not. It will most likely be between 0.2-10.0 hours in the result.

Doing it will require a custom-made script. There are multiple code samples posted to the forums that do something similar, but rounding it to a single digit is a bit tricky. If you're interested I could write it for you, for a small fee. You can contact me privately via [try6767 at gmail.com] to discuss it further.
