title: How to fix unknown timezone Pytz on a Raspberry Pi?
body: <p>I am getting a large traceback error on my Pi3, Pytz can't seem to set the local time. How should I go about solving this?</p>
  
  <p>Here's the line that I think is the issue: </p>
  
  <pre><code>    line 181, in timezone
      raise UnknownTimeZoneError(zone)
  pytz.exceptions.UnknownTimeZoneError: 'SystemV/EST5EDT'
  </code></pre>
  
  <p>Here's the traceback</p>
  
  <pre><code>Traceback (most recent call last):
