var expiredays = "1"; Change to 1 hour instead?

[Captainkewl]

In my JS code, I have this

var expiredays = "1";

which sets a "cookie" to expire in 1 day. However, I want it to expire in 1 hour instead. Is there a way to do that?

Thanks

Here is a better look at more of the relevant code:

function BookMark() {
 
$('#BookmarkImg').animate({ "top": "-81px" }, 1000);
 
baseCookieName = "rwbookmark";
 
var exdate = new Date();
 
var expiredays = "1";
 
exdate.setDate(exdate.getDate() + expiredays);
 
//use of arbritary stop point so no endless loop occurs
 
for (var i = 0; i < 10000; i++) {
 
var curName = baseCookieName + i;
 
if (document.cookie.indexOf(curName) < 0) {
 
document.cookie = curName + "=" + escape(window.location.href) + "[#]contentid=" + document.getElementById("inputContentID").value + "[#]title=" + GetPageTitle() + ";expires=" + exdate.toGMTString() + ";path=/;domain=domain.ca;";
 
break;
 
}

without looking at it too much, the first thing I would try is:

var expirehours = "1";
 
exdate.setDate(exdate.getHours() + expirehours);

or something like that
