creating a timezone aware datetime object returns a wrong timezone

when I create a timezone aware datetime object for 'US/Eastern' and print it out, It shows as if my time zone is -4:56 instead of -4:00

>>> obj = datetime.datetime(2020, 7, 1, 9, 30, tzinfo=pytz.timezone('US/Eastern'))
>>> print(obj)
2020-07-01 09:30:00-04:56

instead of the expected:

2020-07-01 09:30:00-04:00

Am i doing something wrong?

Have a look at dateutil - you can safely construct the tz-aware datetime object using your originally intended method:

import datetime
import dateutil

obj = datetime.datetime(2020, 7, 1, 9, 30, tzinfo=dateutil.tz.gettz('US/Eastern'))
print(obj)
# 2020-07-01 09:30:00-04:00

In Python 3.9, there will be zoneinfo as part of the standard lib for that task.

It is mentioned in the docs that constructing datetime objects doesn't work this way.

You are supposed to do this:

from datetime import datetime

from pytz import timezone

eastern = timezone('US/Eastern')
obj = eastern.localize(datetime(2020, 7, 1, 9, 30))

>>> obj
datetime.datetime(2020, 7, 1, 9, 30, tzinfo=<DstTzInfo 'US/Eastern' EDT-1 day, 20:00:00 DST>)
>>> print(obj)
2020-07-01 09:30:00-04:00
