title: "incorrect parameters" when I want to format CTime in MFC
body: <p>I've got a DataTimePicker in mfc. Now, I want to format the value to a String.
  I format the value with</p>
  
  <pre><code>CTime m_BDate;
  
  m_DataTimePicker.GetTime (m_BDate);
  m_Bithdate= m_BDate.Format ("%d-%m-%Y");
  </code></pre>
  
  <p>But theres a problem. And a pretty strange problem. Whenever the value is &lt; 1970, it doesnt work. So, <strong>01.01.1970</strong> works. <strong>12.31.1969</strong> doesnt. There comes the message "incorrect parameters". I really have no idea why.</p>
  
  <p>Does anyone have any solution?</p>
