>From https://bitbucket.org/schinckel/django-timedelta-field: "If you are
using Django 1.8 or greater (and you really _should_ be), then you should
use the included DurationField() instead of this. This field does not work
with Django 1.10, and will probably not be updated to fix the issue(s).
When migrating TimedeltaField to DurationField using Django migrations,
alter any migrations that have an import to this library to mention the new
field type, this works to prevent Django from crashing when trying to run
the deprecated code."
