How to use timezone offset in Nodejs?

Question

I need the next flow:

var a = new Date(1337324400000, \'Europe/Amsterdam\'); //+2h
console.log(a); // for example 12:00 Mon ...
a.setTimeZone(\'Europe/Kiev\'

See Timezone package in npm. It has everything needed built in and is pure JS and seems to be the best timezone handling library available.

var tz = require('timezone/loaded'),
    equal = require('assert').equal,
    utc;

// Get POSIX time in UTC. 
utc = tz('2012-01-01');

// Convert UTC time to local time in a localize language. 
equal(tz(utc, '%c', 'fr_FR', 'America/Montreal'),
      'sam. 31 déc. 2011 19:00:00 EST');
