I have a python datetime instance that was created using datetime.utcnow() and persisted in database.
For display, I would like to convert the datetime instance retrieved from the database to local datetime using the default local timezone (i.e., as if the datetime was created using datetime.now()).
How can I convert the UTC datetime to a local datetime using only python standard library (e.g., no pytz dependency)?
It seems one solution would be to use datetime.astimezone(tz), but how would you get the default local timezone?
