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.
