Get date time for a specific time zone using JavaScript

It seems that JavaScript's Date() function can only return local date and time. Is there anyway to get time for a specific time zone, e.g., GMT-9?

Combining @​Esailija and @D3mon-1stVFW, I figured it out: you need to have two time zone offset, one for local time and one for destination time, here is the working code:

var today = new Date();  
var localoffset = -(today.getTimezoneOffset()/60);
var destoffset = -4; 

var offset = destoffset-localoffset;
var d = new Date( new Date().getTime() + offset * 3600 * 1000)

An example is here: http://jsfiddle.net/BBzyN/3/

You can do this in one line:

let d = new Date(new Date().toLocaleString("en-US", {timeZone: "timezone id"})); // timezone ex: Asia/Jerusalem

var offset = -8;
new Date( new Date().getTime() + offset * 3600 * 1000).toUTCString().replace( / GMT$/, "" )

"Wed, 20 Jun 2012 08:55:20"


<script>
  var offset = -8;

  document.write(
    new Date(
      new Date().getTime() + offset * 3600 * 1000
    ).toUTCString().replace( / GMT$/, "" )
  );
</script>

You can always get GMT time (so long as the client's clock is correct).

To display a date in an arbitrary time-zone, construct a string from the UTC hours, minutes, and seconds after adding the offset.
