Bug description:
  pytz has served the Python community well for many years, but it is no
  longer the best option for providing time zones. pytz has a non-
  standard interface that is very easy to misuse (see
  https://blog.ganssle.io/articles/2018/03/pytz-fastest-footgun.html);
  this interface was necessary when pytz was created, because datetime
  had no way to represent ambiguous datetimes, but this was solved in
  Python 3.6, which added a fold attribute to datetimes in PEP 495. With
  the addition of the zoneinfo module in Python 3.9 (PEP 615), there has
  never been a better time to migrate away from pytz.
