title: How to correct wrong timezone offset in pytz and django?
body: <p>I am writing a project with django.</p>
  
  <p>I am using timezone 'Asia/ShangHai', when I am getting the datetime object, the offset of the timezone is incorrect and was:</p>
  
  <pre><code>&lt;DstTzInfo 'Asia/Shanghai' LMT+8:06:00 STD&gt;
  </code></pre>
  
  <p>And the offset should be +8:00:00
  AFAICR, the problem was not there before.</p>
  
  <p>How can I solve this problem?</p>
