title: PytzUsageWarning: The zone attribute is specific to pytz's interface; please migrate to a new time zone provider
body: <p>I am writing a simple function that sends messages based on a schedule using AsyncIOScheduler.</p>
  <pre><code>scheduler = AsyncIOScheduler()
  scheduler.add_job(job, &quot;cron&quot;, day_of_week=&quot;mon-fri&quot;, hour = &quot;16&quot;)
  scheduler.start()
  </code></pre>
  <p>It seems to work, but I always get the following message:</p>
  <pre><code>PytzUsageWarning: The zone attribute is specific to pytz's interface; please migrate to a new time zone provider. For more details on how to do so, see https://pytz-deprecation-shim.readthedocs.io/en/latest/migration.html
  PytzUsageWarning: The localize method is no longer necessary, as this time zone supports the fold attribute (PEP 495)
  </code></pre>
  <p>I am not familiar with time in python at all, so I am not really sure what this message is asking me to do. I visited the link provided in the message, but the explanation there is too complicated for me. As I understand, I have to migrate to using PEP495, but how exactly can I do just that?</p>
