title: Pickadate - how to actually use selected date?
body: <p>I'm implementing a pickadate date picker, and it's not clear in the docs how to actually use the date a user selects. Eg I have this written:</p>
  
  <pre><code>$('.datepicker').pickadate({
      onSet: function(context) {
          console.log(context);
      }
  });
  </code></pre>
  
  <p>This produces a weird output (for Sep 8 2015):</p>
  
  <pre><code>Object {select: 1441666800000}
  </code></pre>
  
  <p>How is this output actually usable?</p>
