title: Django: 'unicode' object has no attribute 'year'. What format date/time do I need?
body: <p>I'm getting <code>'unicode' object has no attribute 'year'</code> error from the <code>timesince</code> filter in django. It was working fine previously with strings in this format: <code>"2013-06-20"</code>. However I've now updated the string to include an time element: <code>"2013-06-20T11:20:05.499274"</code> causing this error.</p>
  
  <p>What format do I need to give it to handle the time element? Or do I need to do some extra processing in the view?</p>
