Time on site software?

Ladies & Gentlemen,

Is there such a software that can be ran all day and goes onto your site and clicks on different pages and makes your time on site higher for different keywords? If it was integrated with proxy goblin this would be the best. I wanted to test out the theory that G is now tracking time on site. Instead of not using Google analytics I want to use it to my advantage. Thanks

I would think there was something like this out there! Does anybody have any info. It would be greatly appreciated.

There are scripts out there which can alter time on site + bounce rate ... do some Google searching
