问题 I am creating a DataTimeField no time zone. Soon I am editing this TZ "manually" and then asking to read the value with local TZ. See the end result amends six minutes! Logic: >>> import datetime >>> from django.utils import timezone >>> test = datetime.datetime(2016, 9, 28, 10, 10, 10) datetime.datetime(2016, 9, 28, 10, 10, 10) >>> test = teste.replace(tzinfo=pytz.timezone('America/Sao_Paulo')) datetime.datetime(2016, 9, 28, 10, 10, 10, tzinfo=<DstTzInfo 'America/Sao_Paulo' LMT-1 day, 20:54
