problems converting timestamp to new Date

I have a timestamp of:

1399043514913

Which in reality is Fri, 02 May 2014 15:11:54 GMT but I'm getting Sat, 05 Dec 46303 06:35:13 GMT

How can i correctly convert the timestamp to the Fri, 02 May date?

I'm trying:

var dateTime = new Date(milliseconds * 1000);
var UTCString = new Date(dateTime).toUTCString();

What i really want to end up with is a Date object that i can use getDate(), getMonth(), etc on so i can put the date in any format i like.

Alternatively I'd like a way of converting 1399043514913 to 02/05/2014 15:11:54

Update:

Problem solved thanks to @JensB,

Here's my millseconds to date format converter as a result:

function formatTimeStamp(milliseconds) {

    if (typeof milliseconds === "string")
        milliseconds = parseInt(milliseconds.match(/\d+/g)[0]);

    var dateTime = new Date(milliseconds);
    var dateVar = new Date(dateTime);
    var ISOString = new Date(dateVar).toISOString();
    var UTCString = new Date(dateVar).toUTCString();

    function pad(s) { return (s < 10) ? ("0" + s) : s.toString(); }

    var dateTimeParts = {
        dd: pad(dateVar.getDate()),
        MM: pad(dateVar.getMonth() + 1),
        yyyy: dateVar.getFullYear().toString(),
        yy: dateVar.getFullYear().toString().substring(2, 4),
        HH: pad(dateVar.getHours()),
        mm: pad(dateVar.getMinutes()),
        ss: pad(dateVar.getSeconds())
    };

    var execute = function(string) {

        for (var key in dateTimeParts)
            string = string.replace(key, dateTimeParts[key]);

        return string;
    };

    return {
        ISOString: ISOString,
        UTCString: UTCString,
        date: execute("dd/MM/yyyy"),
        time: execute("HH:mm"),
        dateTime: execute("dd/MM/yy HH:mm:ss"),
        dateTimeParts: dateTimeParts 
    };
}

just running this code (same as in your question) 

var dateTime = new Date(1399043514913);
var UTCString = new Date(dateTime).toUTCString();
alert(UTCString);

Gives me

Fri, 02 May 2014 15:11:54 GMT

Edit as per comment, this work?

$( document ).ready(function() {
    var dateTime = new Date(1399043514913);
    var dateVar = new Date(dateTime);
    var UTCString = dateVar.toUTCString();
    $("#dt").text(UTCString);
    $("#dt2").text("Month: "  + dateVar.getMonth());
    $("#dt3").text("GetDate: "  + dateVar.getDate());
});
