CODE, HTML o PHP Insertado:

(function($) { // Hide scope, no $ conflict

/* Countdown manager. */
function Countdown() {
	this.regional = []; // Available regional settings, indexed by language code
	this.regional[''] = { // Default regional settings
		// The display texts for the counters
		labels: ['', '', '', '', '', '', ''],
		// The display texts for the counters if only one
		labels1: ['', '', '', '', '', '', ''],
		compactLabels: ['y', 'm', 'w', 'd'], // The compact texts for the counters
		whichLabels: null, // Function to determine which labels to use
		timeSeparator: ':', // Separator for time periods
		isRTL: false // True for right-to-left languages, false for left-to-right
};
	this._defaults = {
		until: null, // new Date(year, mth - 1, day, hr, min, sec) - date/time to count down to
			// or numeric for seconds offset, or string for unit offset(s):
			// 'Y' years, 'O' months, 'W' weeks, 'D' days, 'H' hours, 'M' minutes, 'S' seconds
		since: null, // new Date(year, mth - 1, day, hr, min, sec) - date/time to count up from
			// or numeric for seconds offset, or string for unit offset(s):
			// 'Y' years, 'O' months, 'W' weeks, 'D' days, 'H' hours, 'M' minutes, 'S' seconds
		timezone: null, // The timezone (hours or minutes from GMT) for the target times,
			// or null for client local
		serverSync: null, // A function to retrieve the current server time for synchronisation
		format: 'dHMS', // Format for display - upper case for always, lower case only if non-zero,
			// 'Y' years, 'O' months, 'W' weeks, 'D' days, 'H' hours, 'M' minutes, 'S' seconds
		layout: '', // Build your own layout for the countdown
		compact: false, // True to display in a compact format, false for an expanded one
		significant: 0, // The number of periods with values to show, zero for all
		description: '', // The description displayed for the countdown
		expiryUrl: '', // A URL to load upon expiry, replacing the current page
		expiryText: '', // Text to display upon expiry, replacing the countdown
		alwaysExpire: false, // True to trigger onExpiry even if never counted down
		onExpiry: null, // Callback when the countdown expires -
			// receives no parameters and 'this' is the containing division
		onTick: null, // Callback when the countdown is updated -
			// receives int[7] being the breakdown by period (based on format)
			// and 'this' is the containing division
		tickInterval: 1 // Interval (seconds) between onTick callbacks
	};
	$.extend(this._defaults, this.regional['']);
	this._serverSyncs = [];
}

var PROP_NAME = 'countdown';

var Y = 0; // Years
var O = 1; // Months
var W = 2; // Weeks
var D = 3; // Days
var H = 4; // Hours
var M = 5; // Minutes
var S = 6; // Seconds

$.extend(Countdown.prototype, {
	/* Class name added to elements to indicate already configured with countdown. */
	markerClassName: 'hasCountdown',
	
	/* Shared timer for all countdowns. */
	_timer: setInterval(function() { $.countdown._updateTargets(); }, 980),
	/* List of currently active countdown targets. */
	_timerTargets: [],
	
	/* Override the default settings for all instances of the countdown widget.
	   @param  options  (object) the new settings to use as defaults */
	setDefaults: function(options) {
		this._resetExtraLabels(this._defaults, options);
		extendRemove(this._defaults, options || {});
	},
