title: converting excel date into mm/dd/yyyy format
body: <p>I am reading from an excel sheet using poi jar where in there is a date column.If i print out the value of the data cloumn :</p>
  
  <pre><code>cell.getDateCellValue()
  </code></pre>
  
  <p>It gives me value like 3124.0</p>
  
  <p>So i tried with this code to convert to the mm/dd/yyyy format:</p>
  
  <pre><code>SimpleDateFormat sdf = new SimpleDateFormat("MM/DD/YYYY");
  String  s =  sdf.format(cell.getDateCellValue());
  System.out.println(s);
  </code></pre>
  
  <p>But for reading a date 06/30/2001 i got this value as output:</p>
  
  <p>06/181/2001</p>
