When I run the code attached I get the results below. This is not the expected behavior because I was expecting the GMT-5 timezone instead of GMT+5. When I tried to use GMT-5 I had the result of GMT+5. Luckily the timezone names still work ('EST','CST', etc.)

I reproduced something similar in 3.9 with standard library modules: >>> from datetime import datetime >>> from zoneinfo import ZoneInfo >>> zone = ZoneInfo(key='Etc/GMT-3') >>> zone.tzname(datetime(2021, 1, 28)) '+03' |

This isn't a Python bug - it's a quirk of the way that the "Etc/***" timezones are defined. See for example https://en.wikipedia.org/wiki/Tz_database#Area: > In order to conform with the POSIX style, those zone names beginning with "Etc/GMT" have their sign reversed from the standard ISO 8601 convention. In the "Etc" area, zones west of GMT have a positive sign and those east have a negative sign in their name (e.g "Etc/GMT-14" is 14 hours ahead of GMT). |
