title: Converting dateand in XML to UTC timezone with XSLT
body: <p>I have an XML document that has dates in standard ISO 8601 format. Like this:</p>
  
  <pre>
  
  2011-11-29T04:15:22-08:00
  
  </pre>
  
  <p>I would like to convert the time to UTC and the output date in the following form using XSLT:</p>
  
  <pre>
  
  2011-11-29 12:15:22
  
  </pre>
  
  <p>How can it be done?</p>
  
  <p>Thanks in advance.</p>
