var d = new Date(); 
d.setHours(15); 
d.setMinutes(15); 

toLocalTime(d.getTime()) 

.........

/** 
* Converts CDT time to your browser local time. 
* @param time 
* @returns 
*/ 
function toLocalTime(time) { 
    if (time <= 0) 
     return ''; 

    var m = moment.tz(time, 'America/Chicago'); //CDT 

    var tz = jstz.determine(); // Determines the time zone of the browser client 

    m.tz(tz.name()); // Convert CDT to local time 

    return m.format('HH:mm:ss'); 
}
