JavaScript Get Time Central Time Zone

I am using a button to update a form field with a date and timestamp. The issue now is that the request has been made so that anytime these are used they are being updated to the

Solution 1:

Check out moment.js, and its complement moment-timezone.js:

http://momentjs.com

http://momentjs.com/timezone

For example, this will output the current time converted to central timezone:

moment().tz('America/Chicago').format('hh:mm:ss z')
> 03:48:34 CST

moment().tz('America/Chicago').format('hh:mm:ss z Z')
> 03:50:35 CST -06:00

moment().tz('America/Chicago').format()
> 2016-12-05T15:52:09-06:00

Solution 2:

From http://www.techrepublic.com/article/convert-the-local-time-to-another-time-zone-with-this-javascript/6016329

/** 
 * function to calculate local time
 * in a different city
 * given the city's UTC offset
 */
function calcTime(city, offset) {

    // create Date object for current location
    var d = new Date();

    // convert to msec
    // add local time zone offset
    // get UTC time in msec
    var utc = d.getTime() + (d.getTimezoneOffset() * 60000);

    // create new Date object for different city
    // using supplied offset
    var nd = new Date(utc + (3600000*offset));

    // return time as a string
    return "The local time in " + city + " is " + nd.toLocaleString();
}
