Rattail

According to https://pypi.org/project/pytz/ under Issues & Limitations:

This project is in maintenance mode. Projects using Python 3.9 or later are best served by using the timezone functionaly now included in core Python and packages that work with it such as tzdata.

As of now there are several production apps running python 3.8 so while some refactoring is needed, can't really get past this until apps are upgraded to newer python. So not sure how much priority this should get just yet.

It appears "replacement" for pytz will involve:
