title: How to convert a date string with both Etc/GMT into Python date time?
body: <p>Apple is returning a strange format for the expiration date of a receipt:</p>
  
  <blockquote>
    <p>2018-06-18 15:03:55 Etc/GMT</p>
  </blockquote>
  
  <pre><code>from datetime import datetime
  dt = datetime.strptime('2018-06-18 15:03:55 Etc/GMT', '%Y-%m-%d %H:%M:%S %Z')
  </code></pre>
  
  <p>Etc and GMT are both the same.</p>
  
  <p>I have tried to convert it like this into a datetime object, but failed doing so.</p>
  
  <pre><code>ValueError: time data '2018-06-18 15:03:55 Etc/GMT' does not match format '%Y-%m-%d %H:%M:%S %Z'
  </code></pre>
  
  <p>Why are there two time zones defined in the first place? And how can I make Python understanding it?</p>
