Is there a way to tell how much time has passed since the web site has been loaded? I cannot modify the page, but, what I am hoping for, is some sort of statistic or Chrome debug console command that would tell me time with precision in seconds or worst case - minutes.
EDIT:I need the timer on a single page (
site.com/b.html are considered different sites for this purpose). Also, time spent inactive should also be added to timer.
EDIT2: I suppose, exact page load time would work for this purpose too. As in time and date when page was loaded.
