You would be surprised...

>but I think the next question the person who wrote this would ask you, would be, "How do you check for inactivity of the application after the hour passed"?

My hope was to open up a discussion of the subject - which others have done very well. The ut is supposed to be a discussion thread, not an answer thread.

>Also isn't that inefficient to run a timer for an hour checking to see if the hour has expired already without activity?

Not at all... I normally only run one timer at a set interval - say a minute or two, and have things happen based on total time elapsed.
