as3 order directory by date/time - actionscript-3

Question

I need you help to fin a solution to order an array by creation date time.
I try this but this function seems to order only by date and not by time together.
private function triImgDate(folder:Array):void {
var acDirectory:ArrayCollection = new ArrayCollection();
for each (var tmp:File in folder) {
if (!tmp.isDirectory) {
if (tmp.extension != null && ArrayFunction.inArray(tabExt, tmp.extension.toLowerCase()))
{
listeImages.addItem(tmp);
}
}
else {
triImgDate(tmp.getDirectoryListing());
}
}
var dataSortField:SortField = new SortField();
dataSortField.name = "creationDate";
dataSortField.numeric = false;
var numericDataSort:Sort = new Sort();
numericDataSort.fields = [dataSortField];
listeImages.sort = numericDataSort;
listeImages.refresh();
}
So if you can help me.
Best regards

arTempListeImages.addItem(tmp);
objImg.creationDate=tmp.creationDate;
objImg.url=tmp.url;
objImg.pos=arTempListeCompar.length;
arTempListeCompar.addItem(objImg)
}
} else {
triImgDate(tmp.getDirectoryListing());

var dataSortField:SortField = new SortField();
dataSortField.name = "creationDate";
dataSortField.compareFunction = function (a:Object, b:Object) : int {
var na:Number = a.creationDate.getTime();
var nb:Number = b.creationDate.getTime();
if (na < nb)
return -1;
if (na > nb)
return 1;
return 0;
};
var numericDataSort:Sort = new Sort();
numericDataSort.fields = [dataSortField];
arTempListeCompar.sort= numericDataSort;
arTempListeCompar.refresh();
var cpt:int=0;
for each (var objTem:Object in arTempListeCompar) {
listeImages.addItem(arTempListeImages[arTempListeCompar[cpt].pos]);
cpt++;
}
arTempListeImages=[];
arTempListeCompar=[];
acDirectory=[];
}

What you're trying to do here, is comparing twe dates by their string representation, which is obviously not a good way to do it.
you should rather use compareFunction property of the SortField object. Something like that (not tested):
private function triImgDate(folder:Array):void {
var acDirectory:ArrayCollection = new ArrayCollection();
for each (var tmp:File in folder) {
if (!tmp.isDirectory) {
if (tmp.extension != null && ArrayFunction.inArray(tabExt, tmp.extension.toLowerCase())) {
listeImages.addItem(tmp);
}
} else {
triImgDate(tmp.getDirectoryListing());
}
}
var dataSortField:SortField = new SortField();
dataSortField.name = "creationDate";
dataSortField.sortFunction = function(date1:Date, date2:Date):int {
const t1:uint = date1.time;
const t2:uint = date2.time;
if (t1 < t2) {
return -1;
}
if (t1 == t2) {
return 0;
}
return 1;
}
var numericDataSort:Sort = new Sort();
numericDataSort.fields = [dataSortField];
listeImages.sort = numericDataSort;
listeImages.refresh();
}
