Changing date format javascript

I'm pulling some data from two different APIs and I want to the objects later on.

However, I'm getting two different date formats: this format "1427457730" and this format "2015-04-10T09:12:22Z". How can I change the format of one of these so I have the same format to work with?

$.each(object, function(index) {
  date = object[index].updated_at;
}

Try moment.js

var timestamp = 1427457730;
var date      = '2015-04-10T09:12:22Z';

var m1 = moment(timestamp);
var m2 = moment(date);

console.log(m1);
console.log(m2);
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.11.1/moment.min.js"></script>

You can use .format() method in moment to parse the date to whatever format you want, just like: 

m2.format('YYYY MMM DD ddd HH:mm:ss') // 2015 Apr 10 Fri 17:12:22

Check out the docs for more format tokens.

What you probably want in javascript, are date objects.
The first string is seconds since epoch, javascript needs milliseconds, so multiply it by 1000;
The second string is a valid ISO date, so if the string contains a hyphen just pass it into new Date. 

var date = returned_date.indexOf('-') !== -1 ? returned_date : returned_date * 1000;

var date_object = new Date(date);

Making both types into date objects, you could even turn that into a handy function

function format_date(date) {
    return new Date(date.indexOf('-') !== -1 ? date : date * 1000);
}

FIDDLE

Take a look at http://momentjs.com/. It is THE date/time formatting library for JavaScript - very simple to use, extremely flexible.

Here's one option:

var timestamp  = 1427457730;
var date       = new Date(timestamp * 1000); // wants milliseconds, not seconds
var dateString = date.toISOString().replace(/\.\d+Z/, 'Z'); // remove the ms

dateString will now be 2015-03-27T12:02:10Z.
