title: Unix timestamp to XML date time conversion
body: <p>Is there any C++ Library api available which converts  Unix timestamp to XML datatype datetime</p>
  
  <p>eg : </p>
  
  <pre><code>http://books.xmlschemata.org/relaxng/ch19-77049.html
  </code></pre>
  
  <p>I am looking to convert into pattern : 2001-10-26T19:32:52+00:00</p>
  
  <p>I also have access to mysql, so I can get hold of :</p>
  
  <pre><code>mysql&gt; select now();
  +---------------------+
  | now()               |
  +---------------------+
  | 2010-09-28 14:47:47 | 
  +---------------------+
  </code></pre>
  
  <p>I could not find any formatting functions which would fit this.</p>
  
  <p>I just don't prefer string manipulation for this , unless there is no way out....</p>
  
  <p>Cheers!</p>
