Converting tz naive datetime to tz aware jumps from 0 minutes to 58

Question

When I'm converting unaware datetime to aware, it does a weird thing. It adds 58 minutes.

_datetime = datetime.combine(_date,_time)
print(_datetime)
datetime_tz = _datetime.replace(tzinfo='Europe/Bratislava')
print(_datetime_tz)

2020-02-02 12:45:00
2020-02-02 12:45:00+00:58

Do you know why and how to make it work?

That's because you're using `replace` instead of pytz's `localize`. — Mark Ransom, Jan 14 '20 at 23:30

To properly use a timezone object from pytz, you must use the localize function.

>>> import pytz
>>> tz = pytz.timezone('Europe/Bratislava')
>>> _datetime = datetime.combine(_date,_time)
>>> print(_datetime)
2020-02-02 12:45:00
>>> _datetime_tz = tz.localize(_datetime)
>>> print(_datetime_tz)
2020-02-02 12:45:00+01:00

If you don't do this, the timezone object is in an invalid state because it doesn't have a chance to adjust for the date.
