web page on my browser for 1 week straight, would their average time on site go up in google analytics?

Depends on how they handle their analytics.

You need to know if they require a second page view to make that distinction, or if they have a setInterval() that after x seconds it triggers a "view" registration causing it to bump up the stats, which is what you should be doing otherwise your bounce rate will be very high if you have a page that could make someone spend 5 minutes on the page, but rarely click any other pages.
