The date is being returned as milliseconds since epoch. The code below creates a JS date object:

var d = new Date(1245398693390);

var formattedDate = d.getDate() + "-" + (d.getMonth() + 1) + "-" + d.getFullYear();

var hours = (d.getHours() < 10) ? "0" + d.getHours() : d.getHours();

var minutes = (d.getMinutes() < 10) ? "0" + d.getMinutes() : d.getMinutes();

var formattedTime = hours + ":" + minutes;



formattedDate = formattedDate + " " + formattedTime;

Here's a working fiddle.

EDIT 1

Much has changed since this answer was posted so long ago (although the original answer is still valid). A slightly cleaner way of doing this after ES6 introduced const/let and template literals would be:

const d = new Date(1245398693390);

let formattedDate = `${d.getDate()}-${d.getMonth()}-${d.getFullYear()}`;

const hours = d.getHours().toString().padStart(2, 0);

const minutes = d.getMinutes().toString().padStart(2, 0);

const formattedTime = `${hours}:${minutes}`;



formattedDate = `${formattedDate} ${formattedTime}`;

Here's a working fiddle.

You could also make the code a bit more terse by making it only slightly less readable:

function getFormattedDate()  {

    const padWithZero = (num, targetLength) => String(num).padStart(targetLength, '0');

    const d = new Date(1245398693390);

    return `${d.getDate()}-${d.getMonth()}-${d.getFullYear()} ${padWithZero(d.getHours(), 2)} ${padWithZero(d.getMinutes(), 2)}`;

}

Here's a working fiddle.

One could also play with .toLocaleString() and pick out the needed elements from there.
