title: Convert UTC time to python datetime
body: <p>I have numerous UTC time stamps in the following format:
  <code>2012-04-30T23:08:56+00:00</code>
  I want to convert them to python datetime objects but am having trouble.</p>
  
  <p>My code:</p>
  
  <pre><code>for time in data:
      pythondata[i]=datetime.strptime(time,"%y-%m-%dT%H:%M:%S+00:00")
  </code></pre>
  
  <p>I get the following error:</p>
  
  <pre><code>ValueError: time data '2012-03-01T00:05:55+00:00' does not match format '%y-%m-%dT%H:%M:%S+00:00'
  </code></pre>
  
  <p>It looks like I have the proper format, so why doesn't this work?</p>
