title: Default datetime string format with timezone
body: <p>I'm using the default python datetime string format with a JSON webservice.</p>
  
  <p>Then, I'm trying to compare it with an actual datetime. And I'm also using timezone with <code>pytz.utc</code>.</p>
  
  <p>Here is my string date:</p>
  
  <pre><code>print date
  2013-02-26 21:28:37.261134+01:00
  </code></pre>
  
  <p>Trying to convert my string into a datetime (edit for timezone with <code>pytz</code>):</p>
  
  <pre><code>if datetime.strptime(date, '%Y-%m-%d %H:%M:%S.%f+%Z') &lt; datetime.now(pytz.utc):
  </code></pre>
  
  <p>Unfortunately, it doesn't work.</p>
  
  <pre><code>ValueError: time data '2013-02-26 21:28:37.261134+01:00' does not match format '%Y-%m-%d %H:%M:%S.%f%Z'
  </code></pre>
  
  <p>Can anyone tell me the correct syntax for the <code>strptime</code> format, to use my date ?</p>
