[ns] Request for a simple timer example!

[Scott Novich]

Hi all -

I was wondering if someone could help show me how to make a simple timer
that maybe just periodically prints to the console at some interval... I'm
not much of a coder and the manual (11.1.1) was a bit tough for me to follow
with regards of how one can provide an expiration time and start the timer.
Any help would be appreciated!

Best,
Scott
