If a user only views one page, the analytics see that as "no time", even if the user spend 10 minutes on that one page.
Yes, that is what I heard, but if I remember correctly, that "no time" is NOT calculated in the time on site metric.
So if one visitor spends one minute on the page and then goes to a second page on the site tracked with GA, then a second visitor views only one page, and thus is given "no time" on the site, I am FAIRLY sure that the time on site for that page would be one minute (and not 30 seconds).
Hope I am right about this.
