title: Breeze: Filtering by Date only on a DateTime type
body: <p>I'm passing in the following Predicate into an EntityQuery but no results are being returned even tho I have data for the specified date:</p>
  
  <pre><code>// query equals 'Wed Feb 05 2014 00:00:00 GMT+0000 (GMT Standard Time)'
  Predicate.create('createdDateTime', '==', query);
  </code></pre>
  
  <p>This creates the following query in oData:</p>
  
  <pre><code>$filter=CreatedDateTime%20eq%20datetime%272014-02-05T00%3A00%3A00.000Z%27
  </code></pre>
  
  <p>The data held in the database also has the time value: <code>2014-02-05 14:18:02.590</code>, so I guess this is why no data is returned? So my question is, how can I filter just on the Date value, ignoring the time?</p>
