Visitor Duration is not properly appearing

[attachment=1671:piwi1.jpg]
I love piwik , its showing lot of useful data about a visitor, but today i found that its not showing the exact visitor time spent on a particular page.

See the first ip is mine , i went to my friends home and logged into that page for about 40 secs, it shows 0secs. why is that. Is this an area for improvement

What are you saying , is about visitors Action logs, if a visitor clicks one of the other pages you have , then the action is recorded.
