It's not quite free - but the price is very reasonable (about $50) for Peter Blum's Date Control Package (
www.peterblum.com). There are many different kinds of date and time pickers including text boxes and drop downs included in Peter's date control package. None of the free controls are robust. I've tried them all, and settled finally on Peter Blum's package.
