Nope, Google Analytics only increments time on site when the user sends a new pageview. So single-page visits return zero time on site, and GA doesn't record how much time a visitor spent on the final page of their visits.
correct me if I am wrong, but...
If a visitor goes to Page 1 on your site that has GA code on it
Then goes to Page 2, which DOESN'T have GA code on it,
Then goes to Page 3, which DOES have GA code on it
It will then appear to goole that the time the visitor spent on Page 2 (the one WITHOUT GA code on it) was actually spent on the first page (which did have GA code on it).
Or am I totally confused?
