Hey Will thanks for the replies.  My problem isn't finding a regex to do validations of time, it's getting the module to use it.  I have tested this pretty well, and it seems no matter what I do It just reports invalid time format errors when the field type is time.  Now if I change the type to a text field type then my validation expression works.  I just don't like the leght of the text field type.  It realy seems to me that if you select the field type time, then it should tell you why your time format is wrong.  I think what is getting my users is that they need to put in the AM PM.

Sorry for jumping in so late.

The regex validation doesn't work that way, and I assume it is quite useless for your requirements.

The input of time values happens inside a text box, and as a first step the code tests using IsDate() whether the input string is a valid (date) time or not. IsDate() depends on the current locale. For example am/pm is not required for German locale.

Afterwards the input string is parsed to  a DateTime, which again gets transformed to a string in a ISO8601 format (e.g. 10:21 pm -> 0000-00-00:T22:21:00)

This string format can now be examined with the regex. For example, you may enter regexp that enforces full hours. The regular expression has NO influence about the input format . 

Will, please enter your enhancement suggestions to the project's issue tracker, thank you :)
