title: Query mongodb datetime output to be for certain timezone
body: <p>I have a rather basic question.
  the date time for an entry in a collection is saved as</p>
  
  <pre><code>    "lastUpdated": ISODate("2011-12-07T02:46:51.101Z")
  </code></pre>
  
  <p>which is in GMT format. How do I query the entry so that the query output i get is in EST format?
  is this possible in the query itself or do I have to manually subtract 5 hrs (ESt = -5.00 hrs)?
  The query i used is;</p>
  
  <pre><code>    db.Collection.find({Type: 'Reports', patId: 'JOHNSONGARY'}, 
                         {'lastUpdated': 1} )
  </code></pre>
  
  <p>EDIT:
  I use python for querying and am using the returned timestamp as such;</p>
  
  <pre><code>    str(mongo_documents['lastUpdated'].strftime('%Y-%m-%d %H:%M:%S'))
  </code></pre>
  
  <p>How do i deduct 5 hours in this command?</p>
