UTC time off by 53 minutes? about pytz HOT 4 OPEN

Pytz doesn't work with DST and datetime.replace(tzinfo=<timezone>).

Here's how to get the current time in Los Angeles:

import datetime from datetime
import pytz

pdt = pytz.timezone('America/Los_Angeles')
now_utc = datetime.utcnow().replace(tzinfo=pytz.utc)
now_pdt = now_utc.astimezone(pdt)

More info in this Stackoverflow answer and the pytz docs.

OK,
tz_LA = dateutil.tz.gettz('America/Los_Angeles')
works as expected.
I guess pytz provides in-normalized tzinfo due to some advanced usages.

@stub42 I'm also getting the same behavior with 2018.4

from pytz.

Giving,

time_str = "20190101 120000”
timezone = pytz.timezone('America/Los_Angeles')
datetime = ?

How to convert to a datetime, when the string itself is a local time of i.e. Los Angeles?
I'm quite struggling with this, because datetime.replace(tzinfo=) would cause the problem as mentioned above.
