import datetime
import time

import django.db.models as models

from django.utils.dateparse import parse_datetime

class UnixDateTimeField(models.DateTimeField):

# TODO(niklas9):
# * should we take care of transforming between time zones in any way here ?
# * get default datetime format from settings ?
# TODO(niklas9):
# * metaclass below just for Django < 1.9, fix a if stmt for it?
#__metaclass__ = models.SubfieldBase
