python3-pytz-deprecation-shim 0.1.0.post0-3 (s390x binary) in ubuntu lunar

 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; 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.
 .
 However, since pytz time zones are used very differently from a standard
 tzinfo, and many libraries have built pytz zones into their standard time zone
 interface (and thus may have users relying on the existence of the localize and
 normalize methods); this library provides shim classes that are compatible with
 both PEP 495 and pytz's interface, to make it easier for libraries to deprecate
 pytz.
