[AccessD] Military Time

This would mean extra work, but if you think the users will make mistakes
you could always let them enter regular time, mark it as am or pm and
convert it internally to military time.

However, you can use the Short Time format, which is 17:00.  Then all you
need do on a form is use "00:00" for the format string.  Access short time
won't let you enter 2400, which has to be converted to 0000 hours in the
form.
