Mark,
Here is a some sample code that demos using a date field for a label:

// create a feature layer to show earthquakes
var eqUrl = "http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Earthquakes/Since_1970/MapServer/0";
var eq = new FeatureLayer(eqUrl, {

map.addLayer(eq);
/// Setup label properties
var eqLabels = new LabelClass({

// Apply label info to the feature layer
eq.setLabelingInfo([eqLabels]);
});
</script>
</head>
<body class="claro">
<div id="mapDiv"></div>
</body>
</html>
