title: python time.tzname() returning "+-HH" instead of "timezone" in Ubuntu 17.04 Gnome
body: <p>I am not sure this is a problem of the time.tzname attribute since this has started since I moved to Ubuntu 17.04 Gnome. But I would like to now what is the best way to handle this so that my code can keep working on other OSs versions.</p>
  
  <p>Up until now, time.tzname would return something like ['BRT', 'BRTS'] which corresponds to my timezone. But now I am getting ['-03', '-02'] instead.</p>
  
  <pre><code>import time
  time.tzname
  ('-03', '-02')
  </code></pre>
  
  <p>Does anyone know if I can revert it somehow to get the usual ['BRT', 'BRTS'] or this is the new standard?</p>
