Real time screen updates

Real time screen updates

Is it possible to show a time counter decreasing in real-time eg an auction period decreasing from a start date that was set to run for a specified time.

Example

Auction start date 15 Sept 2013 time 9:00am
Auction end date 2 Sept 2013 5pm

When view item you see days, hrs seconds decreasing in real time.

This element is stored and is treated as a variable that can be called referenced in the application.

Thanks for your guidance
