Describe your issue
When using a localized formats the RangeDateTimeFilter does not work.
The linked repository has a localized format for English and is installed via the Django FORMAT_MODULE_PATH setting.
It also has a sample database an Event model. There are 100 instances that have created datetime fields. There is a RangeDateTimeFilter setup to filter these instances and it does not work and appears to fail silently.
