Here are 2 prototypes that you can use to convert a regular ISO-formatted date into a Flash Date object and then, if necessary, to a regular European date format. Both for ActionScript 2. 

Firstly a function to convert a String ISO date to a Date object:

String.prototype.toDate = function():Date {
	var dArr:Array = this.split("-"),
		month:Number = (dArr[1].charAt(0) != "0") ? Number(dArr[1])-1 : Number(dArr[1].charAt(1))-1,
		date:Number = (dArr[2].charAt(0) != "0") ? dArr[2].substr(0,2) : dArr[2].charAt(1);
	if (dArr[2].length > 4 && dArr[2].indexOf(":") != -1) {
		var tArr:Array = dArr[2].substr(3).split(":"),
			flashDate:Date = new Date(dArr[0], month, date, tArr[0], tArr[1], tArr[2]);
	} else {
		var flashDate:Date = new Date(dArr[0], month, date);
	}
	return flashDate;
};
ASSetPropFlags(String.prototype, "toDate", 1);

And secondly a function that turns a Flash Date object into a European date format:

Date.prototype.euDate = function():String {
	var day:String = (this.getDate() > 10) ? String(this.getDate()) : "0" + this.getDate(),
		month:String = (this.getMonth() < 9) ? "0" + Number(this.getMonth()+1) : String(Number(this.getMonth()+1));
	return day + "." + month + "." + this.getFullYear();
};
ASSetPropFlags(Date.prototype, "euDate", 1);

Here’s a test case for both to illustrate the use:

var rawDate = '2007-04-17 23:32:12',
	cDate = rawDate.toDate(),
	EUD = cDate.euDate();
 
/*
    will output:
        Input date is 2007-04-17 23:32:12
        Flash Date is Tue Apr 17 23:32:12 GMT+0300 2007
        EU date is 17.04.2007	
 */
trace("Input date is "+rawDate+"\nFlash Date is " + cDate + "\nEU date is " + EUD);

Both may become handy for those using Flash remoting.
