title: Set created and modified on a listitem through Sharepoint Client Object model
body: <p>I am copying data from one site to another throught the Sharepoint Client Object model. This works for the most fields. The Created and Modified will not change correctly though. </p>
  
  <p>The code is like this:</p>
  
  <pre><code>targetItem.Update();
  targetList.Context.ExecuteQuery();
  targetItem.FieldValues["Created"] = sourceItem["Created"];
  targetItem.Update();
  targetList.Context.ExecuteQuery();
  </code></pre>
  
  <p>I have set the date before, but through debugging I found that the dates were set on the ExecuteQuery so I thought it might be possible to change afterwards.. But no luck.. </p>
  
  <p>Is it possible to set an attribute that passes .SystemUpdate or something like that?</p>
