How to pass JS Date object to List Delegate?

Is there a best practice to pass JavaScript Date objects to QML List Delegates?

If you have a ListModel like:
[CODE]
ListModel {
id: listModel

Component.onCompleted: {
var now = new Date();

var items = [{title: "test1", due: now, description: "subtitle for item1", id: 0}, {title: "test2", due: now, id: 1}];

for (var i=0, l=items.length; i < l; i++) {
listModel.append(items[i]);
}

}
}
[/CODE]

And then want to pass the items to the respected [B]section delegate[/B] to "render" their view and define the "due" property as sections:
[CODE]
Component {
id: delegate

Rectangle {
Text {
text: {
console.log(typeof(section));
console.log("section by delegate: " + section);
var myDate = Date.parse(section);
console.log("myDate type: " + typeof(myDate));
console.log("myDate: " + myDate.toDateString());
return myDate.toString();
}
anchors.left: parent.left
font.bold: true
}
MouseArea {
anchors.fill: parent
onClicked: console.log("clicked: " + section)
}
}

}
[/CODE]

"myDate" will return "NaN". The "due" property is typeof string which I guess is the intended way to pass properties to the delegate (?), but neither Date.parse() nor new Date(section) will give you a new date object in the delegate...
