I need to know the time that a user is in an Page of my site. To do this, I get the time when the user open the Page (in the $w.onReady() function with date.getTime();) and the time when the user leaves the page using a button to go to other page. Until here I have no problems.
But what can I do If the user clicks the "go back" key of the navigator? How can I get the time he does it?
