Moment.js is a freely distributable, third-party JavaScript date library for parsing, validating, manipulating, and formatting dates.

To use the moment.js library in Alloy, require it with the alloy root directory in your require call. For example:

var moment = require('alloy/moment');
var day = moment("12-25-1995", "MM-DD-YYYY");
Ti.API.info("Date:" + day.format("dddd, MMMM Do YYYY, h:mm:ss a")); // --> Monday, December 25th 1995, 12:00:00 am

To change the locale globally, the application calls the moment.locale() function, passing it the new language code.

var moment = require('alloy/moment');
require('alloy/moment/lang/de');
require('alloy/moment/lang/fr');
moment.locale(Ti.Locale.currentLocale); // Set current system locale, as a combination of ISO 2-letter language and country codes.
