title: Get page's messages from a certain date range - Facebook Opengraph API
body: <p>I'm trying to get the messages in a convertation, sent to a Facebook page, from a certain date, via the OpenGraph API.</p>
  
  <p>for that, Im using the parameters "since" and "until".</p>
  
  <pre><code>{conversation_id}/messages?fields=message,from,created_time,shares,tags,attachments&amp;since=4/12/2017 04:00:09 PM&amp;until=4/12/2017 04:18:36 PM
  </code></pre>

  <p>this should return only the messages between these dates in the conversation,
  and used to work both in my code and in the Facebook Graph Explorer.
  but recently i noticed that i get <strong>all the messages</strong> since the beginning of the conversation.</p>
  
  <p>my code uses graph version 2.6, but i tested it on Graph Explorer in other versions as well, all the results are the same.</p>
  
  <p>was there any change in the API that prevents this ability?</p>
