Disposition of pytz package

[Hooverdan96]

Current version: 2022.6 World timezone definitions, modern and historical
Due to ongoing changes of these definitions, this should be either bumped to 2023.3 in the poetry.toml file or, if possible not be required to be pinned anymore.

rockstor-core/pyproject.toml

Line 63 in e965120

pytz = "==2022.6"

With Python 3.9 onwards it is recommended to utilize the built-in functionality instead of this package, which will then allow us to get rid of one more dependency definition.

I assume, since this is currently a django dependency, higher versions of django and python in later Rockstor milestones might resolve the need for this dependency, since, according to @phillxnet we are likely not using this anywhere else in our developments.

For reference:
https://pypi.org/project/pytz/2023.3/

@Hooverdan96 I might of gone with update - but lets keep the fancy "Disposition" Nice.
Thanks for creating this issue.
I'll see to it soon if it's not Assigned before hand.
Adding to agreed Milestone as per side-channel chat.

I favour it's removal form pyproject initially but will have to have a closer look as to if we actually use this directly.

It is currently proposed that we remove our pytz specification all-together. It looks to be a secondary dependency of Django only currently:

This is also in keeping with removing less sensitive (simpler) second order explicit dependency pinning. We have our poetry.lock mechanism still for tracking these changes.

Removing our entry entirely for pytz from pyproject.toml we get the following resolution via poetry:

buildvm:/opt/rockstor # poetry update

@FroggyFlox & @Hooverdan96
Popped the associated pr in as this is a fairly safe update given it's only timezone definitions.
Closing as:
Fixed by #2608
