                var expiry = new Date();
                expiry.setTime(expiry.getTime() + 120);

    } 

Answer 1

This will expire cookie.

if((document.cookie.indexOf('login_time=')<0)){
var date = new Date();
 var minutes = 2;
 date.setTime(date.getTime() + (minutes * 60 * 1000));
 document.cookie = 'login_time=yes; expires=' + date ; 
}
//3.5* 60 * 1000 = 1 minute and 30 seconds
