AJAX Time entry control

Are there any slick AJAX controls available that would allow a user to select a valid time i.e. 4:20PM? If so then how could I incorporate two of those controls to populate a text box with the time difference between the two values. So Control1 = 4:20PM ; Control2 = 4:30PM ; Textbox1 = 10minutes.

Thanks in advance.

I found a good tutorial that pretty much solves my request to validate Time data entry. It uses the MaskedEdit control and the MaskedEditValidator control.

Now I just have to find the VB command that will do the arithmetic.

Nice one.
