ZoneInfo('America/Mexico_City') subtracts one hour less from UTC #138

Hey folks,

Mexico decided not to move any more to summer time from 2023 on (don't ask me why):

ZoneInfo should therefore be adjusted.

To reproduce the error:

from zoneinfo import ZoneInfo from datetime import datetime

utc = datetime.utcnow() mexican_zone = ZoneInfo('America/Mexico_City') local = utc.replace(tzinfo=timezone.utc).astimezone(mexican_zone) print(local)

Thank you!

ZoneInfo does not hard code the zones, they are provided by your operating system or tzdata
