By overriding `uses_datetime_field` to just return `False` things seem to work just fine. I'll mark this as a new feature as it isn't explicitly documented that this should work, and hasn't worked for quite a while (for at least since whenever the `uses_datetime_field property` was introduced)",New feature,closed,Generic views,dev,Normal,duplicate,,,Unreviewed,0,0,0,0,0,0
