Extraction of time from JSON data

I am calling my server code to return json data

$.ajax({
type: "POST",
url: "myurl",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (appdata) {

        var testdata = $.parseJSON(appdata.d);

        console.log(testdata);

        $.each(testdata, function (index, appt) {
        //console.log(appt.PRODUCTID);// works fine
        //console.log(appt.ENTRYDATE);// works fine
        // var starttime=??
    }
});

Here is the console.log(testdata) output

[Object, Object]

0: Object

  PRODUCTID : "51",
  ENTRYDATE : "2013-02-13T12:30:00",
  CATEGORYID : null

__proto__:Object

1: Object

  PRODUCTID : "52",
  ENTRYDATE : "2013-02-13T12:40:00",
  CATEGORYID : null

__proto__: Object
  length: 2
__proto__: Array[0]

How can I extract the time information from ENTRYDATE like (12:30) from the first object's entrydate 2013-02-13T12:30:00

Edit

console.log(appt.ENTRYDATE) works fine, the issue only is how to extract time information from appt.ENTRYDATE


How can I extract the time information from ENTRYDATE like (12:30)

to this: http://jsfiddle.net/Q4vsk/

$.each(testdata, function (index, appt) {
    var $getTime = appt.ENTRYDATE;// works fine
    var $Time = $getTime.substr($getTime.indexOf('T')+1).slice(0, -3);
    console.log($Time); // output will be: 12:30, 12:40
});
