##Usage

An example of usage is as follows:

var sys = require('util');
    var zoneinfo = require('zoneinfo'),
        TZDate = zoneinfo.TZDate,
        countrycodes = zoneinfo.countrycodes;

var d = new TZDate();
    sys.puts(d);
    //=> 2010-09-21 03:18:23 GMT
    sys.puts(d.format("Y-m-d"));
    //=> 2010-09-21
    sys.puts(d.getTimezone());
    //=> UTC
    sys.puts(d.getTimezone(true));
    //=> Etc/UTC
    d.setTimezone("America/Denver");
    sys.puts(d);
    //=> 2010-09-20 21:18:23 GMT-0600
    sys.puts(d.getTimezone());
    //=> MDT
    d.setTimezone("America/Los_Angeles");
    sys.puts(d);
    //=> 2010-09-20 20:18:23 GMT-0700
    sys.puts(d.getTimezone());
    //=> PDT
    d.setTimezone("America/Phoenix");
    sys.puts(d);
    //=> 2010-09-20 20:18:23 GMT-0700
    sys.puts(d.getTimezone());
    //=> MST

zoneinfo.setDefaultTimezone("America/New_York");
    var d = new TZDate("2010-11-08T16:00:00.000Z");
    sys.puts(d);
    //=> 2010-11-08 11:00:00 GMT-0500
    sys.puts(d.getTimezone());
    //=> EST
    d.setTimezone("America/Denver");
    sys.puts(d);
    //=> 2010-11-08 09:00:00 GMT-0700
    sys.puts(d.getTimezone());
    //=> MST
    d.setTimezone("America/Los_Angeles");
    sys.puts(d);
    //=> 2010-11-08 08:00:00 GMT-0800
    sys.puts(d.getTimezone());
    //=> PST
    d.setTimezone("America/Phoenix");
    sys.puts(d);
    //=> 2010-11-08 09:00:00 GMT-0700
    sys.puts(d.getTimezone());
    //=> MST

sys.puts(sys.inspect(zoneinfo.listTimezones()));
    //=> [array of all timezones on the system]
    sys.puts(sys.inspect(zoneinfo.listTimezones("US")));
    //=> [array of all US timezones on the system]

sys.puts(sys.inspect(countrycodes));
    //=> [object of Name: Code pairs]
