I would look at writing custom keystroke, format, and validation scripts using the RegExp to describe the various acceptable input formats for the time. This would be along the lines of the civilian 24 hour time format except one would accept either the ":", ".", or space. One could change the "." or space to the ":' in the keystroke script or use the calculation script.
Unfortunately most mobile device apps do not support date and time formatting and do not support document level scripts. You would need to do a lot of testing to see how PDF Expert works.
Many thanks for your response,
Your assistance is truly appreciated ! 24 hr time format would be preferred as confusion may step in if we use AM/PM.
The separation of hours and minutes isn't an issue however with the other gents also being Navigators, the ":" would be preferred however this doesn't matter in the grand scheme of things to be honest. As long as we can get it to become a green working environment and save wasting such ridiculous amounts of paper the battle will be won regardless.
Not too sure what the calculation script is or how to change the separation indicator, but I'll get to it once we get there :-)
Thanks again for your kind assistance and looking forward to your response.
