• • Can we use this?? https://docs.djangoproject.com/en/dev/ref/utils/#django.utils.timezone.make_aware
    • maybe not
    • (Challenge 1) We need a function that can convert datetime.datetime.now() to datetime.datetime.now().replace(tzinfo=UTC) WITH DST conversion done correctly.
    • (Challenge 2) Is it possible to just change the model instance value and hit save or do we need to change something inside MySQL??
  • Phase 1: UTC datetimes
  • Phase 2: timezone aware datetimes in models
    • Maybe we don't need this???
  • Plan:

1) Change API to assuming UTC input (#762536) 2) Migration and change of defaults to utcnow() 3) Upgrade to Django 1.4 4) Upgrade to timezone aware datetimes
