public function displayDate():void {
var now:Date = new Date();
var day_int:int = now.getDate(); //gets day of the month
var month_int:int = (now.getMonth()+1); // gets month. Months are given from 0 to 11, so you need to do +1 here
var year_int:int = now.getFullYear(); // gets year
var day_string:String;
//display always 2 digits for a month, so '02' instead of just '2' for February
if (day_int < 10) {
day_string = "0" + day_int.toString();
}
else {
day_string = day_int.toString();
}
var month_string:String;
//display always 2 digits for a day, so '02' instead of just '2'
if (month_int < 10) {
month_string = "0" + month_int.toString();
}
else {
month_string = month_int.toString();
}
var year_string:String = year_int.toString();

DateSelect.text = day_string + "/" + month_string + "/" + year_string;
}

<mx:DateField id="DateSelect" formatString="DD/MM/YYYY"/>
