title: Parse CEST/CET time in python
body: <p>I have these date strings:</p>
  
  <pre><code>Fri Oct  7 16:00:09 CEST 2011
  </code></pre>
  
  <p>I want to convert them to UTC. I have tried with this implementation:</p>
  
  <pre><code>def LocalToUtc(localtime):
      return datetime.strptime(localtime, "%a %m %d %H:%M:%S %Z %Y").isoformat() + 'Z'
  </code></pre>
  
  <p>But I get a <code>ValueError</code>:</p>
  
  <pre><code>ValueError: time data 'Fri Oct  7 16:00:09 CEST 2011' does not match format '%a %m %d %H:%M:%S %Z %Y'
  </code></pre>
  
  <p>Any ideas?</p>
