How do I put a Countdown timer display in a form?

I created a testing application with MS Access but I would like to apply a
countdown timer letting the testers know how much time they have to complete
the exam. Has anyone created code that does something like this?

1. Create a form with an unbound text box, and give it these properties:
Format h:nn:ss
Name txtTime

2. Add a second text box where you enter the date and time when the exam is
to end. Set these properites:
Format General Date
Name txtEndTime


2. Set these properties for the form itself:
Timer Interval 10000
On Timer [Event Procedure]

3. Click the Build button (...) beside the On Timer property
Access opens the code window.
Between the "Private Sub..." and "End Sub" lines, enter:
Me.txtTime = Me.txtEndTime - Now()
