JavaScript : Elegant way to convert local timezone date object to UTC timezone date object

Question

I want to convert Date object with local timestamp to Date "object" with UTC timestamp. One of the methods I have found is as follows:

var d = new Date();                  //gives Date object with local timezone
var s_str_utc = d.toUTCString();     //converts it to UTC timezone but 
                                     //is no longer an object but a string

Is there a function to convert directly to object instead. I can always use regex and other stuff to get date and time from s_str_utc but that wont be an elegant way of doing it.

var moment = require("moment");
var d = moment(newDate);
var utc = d.utc();
