How long was my visitor on my website?

[Potterfans]

Hello,
if you use this Code for your Website, your visitor can see how long he was on your page.

<script> 
function time() 
{
i++;
}
var i=0;
setInterval('time()',1000);
window.onunload=now;
function now()
{
alert("You was "+i+" seconds here");
}
</script>

Have fun
