title: Sort a date column in jqGrid
body: <p>I am using <a href="http://www.trirand.com/jqgridwiki/doku.php?id=start" rel="nofollow">jqGrid</a> for displaying records in a user interface, and I want to sort the date column. Which returns me the date in the form of <code>Sat, Sep 1, 01:41 AM</code>. How can I do that with jqGrid?</p>
  
  <p>My Colmodel for that column is:</p>
  
  <pre><code>{name:'transactiontime', index:'transactiontime',  sorttype:'text', align:"right"},
  </code></pre>
