America/Sao_Paulo to UTC is -3:00 but pytz is returning -3:06

[samuelrohr]

As a checked before 1914 the timezone in Sao Paulo was -3:06 but it changed on that year.
The current version of pytz is returning the timezone as it's -3:06 from UTC instead of -3:00

You can check buy using this:

from datetime import datetime
import pytz

now = datetime(2021, 2, 3, 15, 0, 0, 0, pytz.timezone("America/Sao_Paulo"))
as_utc = now.astimezone(pytz.UTC)

You are not supposed to pass the result of pytz.timezone(…) to datetime, but should pass the datetime to its localize method.

from datetime import datetime
import pytz

now = datetime(2021, 2, 3, 15, 0, 0, 0)
dt_local = pytz.timezone("America/Sao_Paulo").localize(now)
as_utc = dt_local.astimezone(pytz.UTC)

@samuelrohr We opted for zoneinfo instead. Hope that helps! :D https://docs.python.org/3/library/zoneinfo.html
