[Bug 2101044] [NEW] Please migrate from pytz to zoneinfo or dateutil.tz

[Benjamin Drung]

Public bug reported:

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.
