title: What's wrong with this tzinfo variable?
body: <p>I have this line of code:</p>
  
  <pre><code>datetime.datetime.fromtimestamp(0, "&lt;DstTzInfo 'US/Pacific' PST-1 day, 16:00:00 STD&gt;")
  </code></pre>
  
  <p>And it keeps giving me this error:</p>
  
  <pre><code>TypeError: tzinfo argument must be None or of a tzinfo subclass, not type 'str'
  </code></pre>
  
  <p>What is <code>tzinfo</code> and where does it go?</p>
