Actionscript: Sorting ArrayCollection by date: YYYY-MM-DD

Question

I have an ArrayCollection of Objects. Each Object has the following keys/values:

{date: 2009-12-01, visits=13555, bouceRate=45}
{date: 2009-12-05, visits=46955, bouceRate=45}
{date: 2009-12-06, visits=13685, bouceRate=45}
{date: 2009-12-02, visits=13685, bouceRate=45}
{date: 2009-12-04, visits=68755, bouceRate=45}
{date: 2009-12-03, visits=35875, bouceRate=45}

I need to sort this ArrayCollection by date, so it would be from past to present - like so:

{date: 2009-12-01, visits=13555, bouceRate=45}
{date: 2009-12-02, visits=13685, bouceRate=45}
{date: 2009-12-03, visits=35875, bouceRate=45}
{date: 2009-12-04, visits=68755, bouceRate=45}
{date: 2009-12-05, visits=46955, bouceRate=45}
{date: 2009-12-06, visits=13685, bouceRate=45}

I have tried the following with no prevail (not sorting):

var dateSort:Sort = new Sort();
    dateSort.fields = [new SortField("date", false, false, true)];

newAreaChartData.sort = dateSort;
newAreaChartData.refresh();

// traceout
for (var i:int = 0; i <newAreaChartData.length; i++)
    trace ("Object #" + i + ": " + ObjectUtil.toString(newAreaChartData.getItemAt(i)));

Answer 1

This worked for me:

for(i = 0; i < newAreaChartData.length; ++i) {
    newAreaChartData[i].formattedDate = getActualDate(newAreaChartData[i].date);
    newAreaChartData[i].dateTime =    newAreaChartData[i].formattedDate.time;
    trace(newAreaChartData[i].dateTime);
}

    var dateSort:Sort = new Sort();
    dateSort.fields = [new SortField("dateTime", false, false, true)];
    newAreaChartData.sort = dateSort; 
    newAreaChartData.refresh();

for (var i:int = 0; i <newAreaChartData.length; i++)
    trace ("Object #"+ i + ": " + ObjectUtil.toString(newAreaChartData.getItemAt(i)));
