should probably be migrated to an inclusion tag to allow a source timezone that isn't the site specific TIME_ZONE.

This code assumes that your database stores dates according to the django.conf.settings.TIME_ZONE variable.

Yes.. this assumes that dates are stored in the database according to system time. On my systems the system time of a server is always UTC therefore avoiding problems with datetime (no tz info) columns in backend databases having no timezone information and stored according to the database or system timezone information. I find it a good practice to always use UTC for any stored information and always retrieve information as UTC and localize the date during display.

from django import template
from django.conf import settings

import pytz

register = template.Library()

@register.filter
def astimezone(date, destination=None):

    if not destination:
        destination = settings.TIME_ZONE

    if date.tzinfo:
        return date.astimezone(pytz.timezone(destination))
    else:
        return pytz.timezone(settings.TIME_ZONE).localize(date).astimezone(pytz.timezone(destination))
