Cookie doesn't expire!!

[Anon]

Hi!

I set the cookie to expire after 60 sec. but it expires after 5 minutes!

code:
if($HTTP_COOKIE_VARS["popunder"] != "yes")
{
$kem=1;
setcookie("popunder","yes",time()+60);
}
}

Why is that?

Thanks for your answer!

It could most likely be a cache problem. I have had this happen to me before.
