title: jqGrid shows 13 digit number rather than format date
body: <p>My jqGrid is showing (1303153262000) on the initial grid load. However when the column is sorted the date is correctly formatted to (Aug 18 11:43 AM). Is there a way to get the grid to do this formatting automatically when it loads?</p>
  
  <p>This is exactly what the date looks like as it is returned from the server (2011-04-18 19:01:02).</p>
  
  <p>Here is the jqGrid column model i am using:</p>
  
  <pre><code>jQuery("#list4").jqGrid({
  datatype: "local",
  height: 250,
  colNames:['Original ID','Date Created', 'Type', 'Title'],
  colModel:[  
  {name:'Id',index:'Id'},
  {name:'cDate',index:'cDate', width:120, sorttype:'date', formatter:'date',     formatoptions: {srcformat:'M d h:i', newformat:'M d g:i A'}},  
  {name:'xData',index:'xData', width:120}, 
  {name:'zData',index:'zData', width:140}
  ],
  rowNum: 1000,
  multiselect: true,
  toolbar: [true, "top"]
  });
  </code></pre>
  
  <p>Any help would be greatly appreciated! Thanks.</p>
  
  <p>Edit:</p>
  
  <p>@Oleg here is what the data looks like on the server side:</p>
  
  <pre><code>2011-04-18 19:01:02
  2011-04-18 19:01:28
  2011-01-07 01:00:20
  2011-04-18 19:01:02
  2011-04-18 19:01:28
  2011-01-07 01:00:20
  2011-06-29 22:20:29
  2011-06-29 21:47:55
  </code></pre>
  
  <p>And here is what it looks like when returned into the jqGrid:</p>
  
  <pre><code>Test: 1303153262000
  Test: 1303153288000
  Test: 1294362020000
  Test: 1303153262000
  Test: 1303153288000
  Test: 1294362020000
  </code></pre>
  
  <p>Am i going to have to create a new array with the returned results with a function to change the epoch date to the date format i want? Having to do so would not make sense as jqGrid obviously has that functionality, but only when a user clicks sort. Is there a way to make jqGrid do this when the page loads?</p>
  
  <p>I pulled this from eclipse. I am using a list/array called NotesArray. This is the array that is returned from the server:</p>
