title: Merge file from one barnch to another branch in Clearcase
body: <p>I want to merge a file from one branch to another branch in clearcase,<br>
  for example from <code>Offshore</code> branch to <code>DEV</code> branch.</p>
  
  <p>I want to merge the file with its modification time as it is.</p>
  
  <p>If the modification date of a file (<code>example.asp</code>) is <code>12-02-2011</code>, after merging the file in <code>DEV</code> branch, the modification time for the file (<code>example.asp</code>) in <code>DEV</code> branch should hold the same modification time (<code>12-02-2011</code>).</p>
  
  <p>Which view should I take?<br>
  how should I do merge? </p>
  
  <p><strong>Note:</strong> I tried <strong><em>preserve modification time</em></strong> option while checkin and checkout during merging.</p>
