title: How to get notifications that have Edge date property greater than last visited date in Titan using Gremlin?
body: <p>I'm having user vertices which have incoming Notification edges as follows:</p>
  
  <p>code am using to get notifications </p>
  
  <pre><code>g.v(17929472).outE('Notification')
  </code></pre>
  
  <p>Response I'm getting :</p>
  
  <pre><code>{
    "success": true,
    "results": [
      {
        "Type": "UserReaction",
        "PostedDate": "2016-04-15T09:03:42.8391677Z",
        "NotificationInitiatedByVertexId": "2304",
        "_id": "c7bb4-aoagw-sgl-aoao0",
        "_type": "edge",
        "_outV": 17929472,
        "_inV": 17929728,
        "_label": "Notification"
      }
    ],
    "version": "2.5.0",
    "queryTime": 15.310751
  }
  </code></pre>
  
  <p>Whenever user view the notification i'm saving the last seen date and want to use that date to get all notification that is present after that date.</p>
  
  <p>I've tried :</p>
  
  <pre><code>g.v((5124096).outE).outE.has('PostedDate',T.gte, 2016-04-15T07:52:31.6979843Z).inV
  </code></pre>
  
  <p>but it is giving error.</p>
