title: wxpython > DatePickerCtrl obj - How can I convert 'year' from 2 digits into 4 digits?
body: <p><strong>PROBLEM</strong></p>
  <blockquote>
  <p>In GUI DatePickerCtrl obj, the date format is: mm/dd/yyyy</p>
  <p>if I get the DatePickerCtrl obj value, the date format is: mm/dd/yy hh:mm:ss</p>
  </blockquote>
  <p><strong>CODE snippet</strong></p>
  <pre><code>datePicker = wx.adv.DatePickerCtrl( frame, wx.ID_ANY, wx.DefaultDateTime)
  print datePicker.GetValue() # This outputs  11/20/15 14:20:55
  </code></pre>
  <p>I can convert to string and slice <code>[:-8]</code> but I cannot convert <strong>'15'</strong> into <strong>'2015'</strong></p>
  <p><strong>CURRENT</strong></p>
  <pre><code>11/20/15
  </code></pre>
  <p><strong>DESIRED</strong></p>
  <pre><code>11/20/2015
  </code></pre>
