Updating the Cookie for specific time interval

If you want to update the cookies after some time interval using the time then call the below function.
Timer should run with the interval of less than 11 minutes.

updateCookieValue  :  function () {
    var cookies = document.cookie.split(";");
if (cookies.length > 0) {
var nTime = new Date();
//add 11 mins to current time so that the recursive call to update cookie
             (with interval 10 mins)
//gets executed before the cookie gets expired ( 11 * 1000 * 60)
             // time added in millisecond
nTime.setTime(nTime.getTime()+660000);
for (var i = 0; i < cookies.length; i++){
var name = cookies[i].split("=")[0];
name = name.trim();
var value = cookies[i].split("=")[1];
if((name == " cookie_0") || (name == " cookie_1")){
document.cookie = name + "=" +escape( value ) +";expires="
                      + nTime.toGMTString()+";path=/;domain=";
}
        }
}
}
