[Bug 1995452] [NEW] Invalid daylight saving time info for 'Europe/Dublin'

[Kamila]

Public bug reported:

I'm trying to check if daylight saving time is in effect for the
'Europe/Dublin'. Executing the following line:

datetime.datetime.now(pytz.timezone('Europe/Dublin')).dst()

is giving 0 as a result, which is incorrect because during the day that
I was executing the command (2022/10/17) was still daylight saving time
in effect so the function should return a dst offset value.

The function below also returned the wrong result (False instead of
True) for the date 2022/10/17:

import pytz
from datetime import datetime, timedelta

def is_dst(zonename):
    tz = pytz.timezone(zonename)
    now = pytz.utc.localize(datetime.utcnow())
    return now.astimezone(tz).dst() != timedelta(0)

is_dst('Europe/Dublin')
