title: jqgrid datetime formatting
body: <p>I have a spring MVC java application and I'm serializing joda DateTime to json.</p>
  
  <p>When I examine the output through the browser the DateTime serialized data looks like this:</p>
  
  <pre><code>startDate: 1323147660000
  </code></pre>
  
  <p>I'm not sure which format this data is in.  I've tried many different combinations of srcformat and newformat format options including the following based on <a href="https://stackoverflow.com/questions/8212008/in-jqgrid-how-to-format-timestamp-to-dd-mm-yyyy-format">this post</a>:</p>
  
  <pre><code>{srcformat:'U', newformat:'m/d/Y'}
  </code></pre>
  
  <p>My hunch is that this is the number of milliseconds since the epoch but I'm not sure how to use it correctly within jqgrid.</p>
  
  <p>Thanks in advance for any help.</p>
