Datepicker - bug

Datepicker - bug


Datepicker breaks if you add methods to the date object.
Specifically, the following code breaks it
Date.prototype.getMonth = function() {
    var month = (this.getUTCMonth()+ 1) + "";
    if(month.length == 1) {
        month = "0" + month;
    }
    return(month);
}
Date.prototype.getDate = function() {
    var date = this.getUTCDate() + "";
    if(date.length == 1) {
        date = "0" + date;
    }
    return(date);
}
