Multiple conflicting time zone configurations

Running on Ubuntu 16.04 I’m getting this error with tzlocal >= 4.0.1

cat /etc/timezone America/Denver

cat /etc/sysconfig/clock ZONE=“America/Denver” UTC=false ARC=false

I don't know why it's checking /usr/share/zoneinfo/Navajo?

OK, no new issues for a few days, I released this as 4.1.

@davejennings That great! The warnings are expected. Are you explicitly using pytz? If not you may want to modify your code to use the standard datetime way of dealing with timezones instead. It’s been updated to handle the cases that it could not handle earlier, so the pytz API isn’t needed any more.

IIRC (it’s a year since I did this, I may misremember) instead of localize() you use the replace() function on the datetime to make a naive datetime into a timezone aware one, and you no longer need to call normalize() after converting to another timezone.

https://pytz-deprecation-shim.readthedocs.io/en/latest/migration.html has more information on the differences. But there is no panic in doing this, I won’t drop the pytz shim for at least a year, probably longer since I’m lazy.
