اضافه کردن زمان به کوکی در این کد جاوا اسکریپت

[Milad123 285]

سلام

این کد یک کد پاپ آپ نیو تب هستش که هیچ مشکلی هم نداره فقط زمانش مشکل داره!

میخوام کوکی توی این کد جوری تنظیم بشه که هر 24 ساعت یکبار برای هر کاربر باز بشه

<script type="text/javascript">
var needpop = 1;
var vc_cn = "jot9843504";
var vc_url = "http://www.site.com";
if (readCookie(vc_cn)) {
needpop = 0;
}else{
needpop = 1;
}
var PopWidth = 1024;
var PopHeight = 768;
var PopTargetingMethod = 100;
var PopUseDivLayer = 1;
var RTSDomain = vc_url;
var debugDomain = vc_url;
var Page_Popped = false;
var Page2_Popped = false;
var Page_Loaded = false;
var Page_Enter;
var MySiteDomain = window.location.href.split('/');
if (needpop == 1) {
InitPop()
}
function InitPop() {
Page_Enter = new Date();
if (window.captureEvents) {
window.captureEvents(Event.CLICK);
window.onclick = LoadStandardPop
} else document.onclick = LoadStandardPop
}
function SiteEnter() {
Page_Loaded = true
}
function createCookie(name, value, days) {
if (days) {
var date = new Date();
date.setTime(date.getTime()+(12*60*60*1000));
var expires = "; expires=" + date.toGMTString()
} else var expires = "";
document.cookie = name + "=" + value + expires + "; path=/";
}
function readCookie(name) {
var ca = document.cookie.split(';');
var nameEQ = name + "=";
for (var i = 0; i < ca.length; i++) {
var c = ca[i];
while (c.charAt(0) == ' ') c = c.substring(1, c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length)
}
return null
}
function RetrieveCount() {
var cookieName = vc_cn;
var popSuccesses = readCookie(cookieName);
if (popSuccesses != null) popSuccesses = parseInt(popSuccesses);
else popSuccesses = 0;
return popSuccesses
}
function IncrementCount() {
var cookieName = vc_cn;
var popSuccesses = readCookie(cookieName);
if (popSuccesses != null) createCookie(cookieName, parseInt(popSuccesses) + 1, 1);
else createCookie(cookieName, 1, 1)
}
function LoadStandardPop() {

var pLoaded = false;
