title: How do you convert a python time.struct_time object into a ISO string?
body: <p>I have a Python object:</p>
  
  <pre><code>time.struct_time(tm_year=2013, tm_mon=10, tm_mday=11, tm_hour=11, tm_min=57, tm_sec=12, tm_wday=4, tm_yday=284, tm_isdst=0)
  </code></pre>
  
  <p>And I need to get an <a href="http://www.w3.org/TR/NOTE-datetime" rel="noreferrer">ISO string</a>:</p>
  
  <pre><code>'2013-10-11T11:57:12Z'
  </code></pre>
  
  <p>How can I do that?</p>
