/^\\d{1,2}[:][0-5][0-9]$/

    Assuming you are working in 12 hour time, 0 is not a valid hour and should also be excluded (as pointed out by Jon). Here is a basic solution:

    /^(0?[1-9]|1[012]):[0-5][0-9]$/
    

    A 24-hour time regex matcher that works similarly:

    /^([01]?[0-9]|2[0-3]):[0-5][0-9]$/
