[AccessD] Calendar Controls AND TIME Controls

I always hear about Calendar Controls and have used a few of them.  I was
wondering if anyone out there has a Time control.  I have a very time
sensitive application where the technicians have to enter Date and Time on
and Date and Time off.  The time is essential to knowing how long the piece
ran with or without defects in the product to know whether to fix it or use
that mold as a template for others if it was working properly over a long
period of time (long could be 16+ hours due to the harsh environment).  

Anyway, back to my question.  I have a Date/Time field for ON and OFF,
currently I have a text box that is populated with a pop up calendar or by
typing in text, works great.  I also have another unbound field that is used
purely for Time entry, of which the user must type it in as ##:## AM/PM,
then upon exit it concatenates that information with the Date information to
make a complete Date/Time field.. Does anyone know of a Time control or a
better way to achieve this type of functionality other then the Date and
Time Active X control.

Thanks in Advance,
