title: AngularJS ui-grid DateTime column
body: <p><br/>
  I would like to have a column in my angularjs ui-grid that displays a datetime eg"dd/MMM/yyyy hh:mm:ss".<br/>
  I have found heaps of documentation on using date fields, but there seems to be nothing for datetime fields. When I use the following columnDefs, the TimeDown field renders blank.<br/>
  Has anyone had any success with datetime columns?<br/>
  Thanks in advance.<br/>

  <pre><code>$scope.gridOptions = {
      enableRowSelection:true,
      columnDefs: [
          { name: 'IncidentRef',displayName:'Incident', width:'20%' },
          { name: 'Areas' },
          { name: 'TimeDown', type:'datetime',cellFilter: 'datetime:"dd MMM yyyy hh:mm"'},
          { name: 'TotalNumberOff', displayName: 'Total off', width: '10%' }
      ]
  };
  </code></pre>
