I have an ArrayCollection that I'd like to sort by date and then time (in case there's two items with the same date). I've got it sorting by date fine (YYYY/MM/DD) but I can't figure out the time bit, time is in 24 hour format so the code would be basically the same as for the date.
This is the code I used for the date sorting, it works fine.
import mx.collections.SortField;
import mx.collections.Sort;
private function sort():void
{
var dataSortField:SortField = new SortField();
dataSortField.name = "date";
var arrayDataSort:Sort = new Sort();
arrayDataSort.fields = [dataSortField];
reminderXMLArray.sort = arrayDataSort;
reminderXMLArray.refresh();
}

As there are two separate fields that you want to sort on you can just use the Sort object's fields Array to add two sort fields:
var sort:Sort = new Sort();
var fields:Array = [ new SortField("date"), new SortField("time") ];
sort.fields = sort;

You can use this code to sort by date and time:
private function sort():void
{
var dataSortField:SortField = new SortField();
dataSortField.name = "date";
dataSortField.compareFunction = function (a:Object, b:Object) : int {
var na:Number = a.date.getTime();
var nb:Number = b.date.getTime();
if (na < nb)
return -1;
if (na > nb)
return 1;
return 0;
};
var arrayDataSort:Sort = new Sort();
arrayDataSort.fields = [dataSortField];
reminderXMLArray.sort = arrayDataSort;
reminderXMLArray.refresh();
}
