Start a new project with {{{django-admin startproject}}}, then start a
shell with {{{./manage.py shell}}} and execute these commands:
{{{#!python
from datetime import datetime
import sys
from django.template import Context, Template
import pytz
# Set adatetime to 2015-10-03 02:00 EEST (+0300)
athens = pytz.timezone('Europe/Athens')
adatetime = athens.localize(datetime(2015, 10, 3, 2, 0))
# Render that date in a template
template = Template(
'Take note of this date: {{ adatetime|date:"Y-m-d H:i e (O)" }}')
result = template.render(Context({'adatetime': adatetime}))
sys.stdout.write(result)
}}}
**Result:** `2015-10-02 23:00 UTC (+0000)`
**Expected:** `2015-10-03 02:00 EEST (+0300)`
These are actually the same time displayed in different time zones. Django
chooses to display the time in the `TIME_ZONE` setting. I thought it would
be more logical to leave an aware datetime untouched.
If this behavior is correct: How am I going to do what I want, which is to
render the aware datetime in its own time zone?
