This will work in code-behind, and allows the minutes and seconds to
be optional:
(0?[1-9]|1[012])(:[0-5]\d){0,2}(?i:\ [A|P][M])
This forces the minutes and seconds to be included:
(0?[1-9]|1[012])(:[0-5]\d){2}(?i:\ [A|P][M])
To you in a regex validator you need to a little less concise, since
ithe ?i: option setting causes a javascript error:
(0?[1-9]|1[012])(:[0-5]\d){2}(?i:\ [A|a|P|p][M|m])
