New Filter Experience - Advanced Filtering on a Date only column includes a time bound. If the column is date only, it should only have the date portion in the filter experience.
I agree with this. If only working with only dates, when a user selects any time other than 12:00am the report will no longer filter on the selected date. The user is also mislead into thinking that the time filtering is relevant.
E.g. if user selects '31/12/2018 12:00am' the report will filter to 31/12/2018, but if 12:01am is selected then no data will show for 31/12/2018.
