Use DateTime.ParseExact to convert it to a DateTime, specifying the
format.

You can subtract one DateTime from another to get a TimeSpan
representing the difference between the two.

I would split your string to two substrings, one for the hours and one for
the minutes. I don't think there is a standard for 1345 or 13:45. Once
split, then I would use integer.TryParse(sHours, out hours); and
integer.TryParse(sMinutes, out minutes);

You should be using DateTime.Parse (or possibly DateTime.ParseExact) to
get the DateTime that reflects your first and second time, then just
subtract one from the other and you'll have your TimeSpan. The only
catch may be the handling of military time, but it should work.

example:

DateTime a = DateTime.Parse("10:59:44 PM");
DateTime b = DateTime.Parse("14:12:10");

TimeSpan c = b - a;

Thanks, guys! This is twice I have used this group as a 'last resort'
and twice you have come through for me. Guess I should check here first
next time.

I had to used the DateTime.ParseExact() in my clsMilitary.cs code and
the DateTime.Parse() in my militaryTimeDiff method in the frmMain.cs
code. Don't know if that is how its suppose to be but it works.
