Hola emprear esta es la funcion:
Código Javascript
:
Ver original(function($) {
$.fn.countdown = function(toDate, callback) {
var handlers = ['seconds', 'minutes', 'hours', 'days', 'weeks', 'daysLeft'];
function delegate(scope, method) {
return function() { return method.call(scope) }
}
return this.each(function() {
// Convert
if(!(toDate instanceof Date)) {
if(String(toDate).match(/^[0-9]*$/)) {
toDate = new Date(toDate);
} else if( toDate.match(/([0-9]{1,2})\/([0-9]{1,2})\/([0-9]{2,4})\s([0-9]{1,2})\:([0-9]{2})\:([0-9]{2})/) ||
toDate.match(/([0-9]{2,4})\/([0-9]{1,2})\/([0-9]{1,2})\s([0-9]{1,2})\:([0-9]{2})\:([0-9]{2})/)
) {
toDate = new Date(toDate);

} else {
throw new Error("Doesn't seen to be a valid date object or string")
}
}
var $this = $(this),

}
// Calculate the time offset

}
