Not that I know of, but the military time is pretty easy to figure out. It's the same as standard time up until 1 P.M. (other then the first 0 being in front of the hour before 10 A.M.), then after 1 it's 13:00, 2 P.M. is 14:00, 3 P.M. is 15:00 and so on.
I prefer 12 hour time personally. Only reason I know 24 hour time is because we use AS400 at work to keep track of all sorts of different parts as they move throughout the building/production process, and all the time stamps are in 24 hour. So you just get used to it after awhile.
24 Hour Time After 52 years using 24 hour time it is normal to me. My digital watch is on it. Also I wriet my dates correctly. Today is 14 Nov. 2009. Any important date i.e. the deed on your home will be day, month, year. Texasjack OLD GI
