I think you should take a look to these widgets: 

https://widgets.jotform.com/widget/timer

https://widgets.jotform.com/widget/fancy_timer

https://widgets.jotform.com/widget/time_tracker

They will count the time that user takes to fill the form, if you want to set a defined time that user has to complete it, you can use widgets on this link: http://widgets.jotform.com/search/countdown 

Here is a guide that will help you to add a widget to your form: How-to-Add-a-Widget-to-your-Form
