Pytz Localise on Aware Datetime

问题

I am trying to convert an aware datetime (UTC) to a local time using pytz.

I was using this snippet of code, which lead to the time being off by a few minutes

new_timezone = pytz.timezone(local_timezone)
new_datetime = entry[1].replace(tzinfo=timezone.utc).astimezone(tz=new_timezone)

I tried to do this, but get an error that it is not a naive datetime:

local_timezone_pytz.localize(entry[1])

回答1:

use astimezone, e.g.:

import datetime
import pytz

dt = datetime.datetime.now(datetime.timezone.utc)
# datetime.datetime(2020, 10, 22, 5, 48, 5, 806183, tzinfo=datetime.timezone.utc)

dt_est = dt.astimezone(pytz.timezone('US/Eastern'))
# datetime.datetime(2020, 10, 22, 1, 48, 5, 806183, tzinfo=<DstTzInfo 'US/Eastern' EDT-1 day, 20:00:00 DST>)

Note that this is not specific to pytz; you can also supply a timezone object from dateutil.tz.gettz or zoneinfo.ZoneInfo to astimezone.
