Timer that closes the page after set time.

I am looking for a timer that closes the page after so many minutes for a timed exams.

Is there a plug in or an outside app that can be integrated? Thank you.

We have a countdown widget that you can find here: http://widgets.jotform.com/widget/countdown that can help you to accomplish this.

This widget would not allow the submission of the form if the timer gets to zero.

Please check it out and let us know if it could fit your needs.
