title: Apache POI Date to String issue
body: <p>I'm using apache POI for reading excel.I have one date field in my excel file with date format as "MM/dd/yy". I would like to read all the cells as String. so I set all the cell type to string by using "<strong><code>cell.setCellType(Cell.CELL_TYPE_STRING);</code></strong>".  When this cell is converted into String the value i see for the date field is 41886. Please let me know if I'm missing anything.</p>
  
  <p>Thank you.</p>
