title: angularjs date filter not formatting my json value
body: <p>I have a service that returns json like so:</p>
  
  <pre><code>"Results":[{"Id":"1","SomeDate":"2/19/2013 10:34:04 PM"}
  </code></pre>
  
  <p>When i try to format using binding, it doesnt work - it just displays the string above:</p>
  
  <pre><code>{{values.SomeDate| date:'mediumTime' }}
  </code></pre>
  
  <p>However, it works if i just pass in this format:</p>
  
  <pre><code>{{ '1997-03-01T00:00:00+01:00' | date:'mediumTime'}}
  </code></pre>
  
  <p>What is the best way to fix this?</p>
