Question: Loop in the background that displays time[real] every 600 seconds

I'm not sure if this can be done in a current worksheet but I'm pretty sure it has to be done in a separate worksheet. 

What I'm trying to do is set up a running loop that automatically displays the amount of time the maple kernel has been in use, say every 600 seconds or so.  I know I need to use time[real] but I need it continuously running if I want it to display times, right?  Which means I need it to run in a separate worksheet I think. 

Any ways that I can do this with maple?
