 !     Error while running '$ python manage.py collectstatic --noinput'.
       See traceback above for details.
       You may need to update application code to resolve this error.
       Or, you can disable collectstatic for this application:
          $ heroku config:set DISABLE_COLLECTSTATIC=1
       https://devcenter.heroku.com/articles/django-assets
 !     Push rejected, failed to compile Python app.
 !     Push failed

Notice the error:

These timezones are case-sensitive, I don’t know where it’s getting that from, but that’s not going to work.

Try adding the following to your settings.py
TIME_ZONE = 'Africa/Lagos'

See Settings | Django documentation | Django and List of tz database time zones - Wikipedia
