Change views exposed filter format I am build a JSON export using a View in Drupal 8. Problem is that the parameters for retrieving the json doesn't seem to work as I would want.

In my View I need use two exposed filter criteria to select a date range.  Both fields are Date and Time fields. When clicking on one of the criteria I have created it says:


  Value type
  
  A date in any machine readable format. CCYY-MM-DD HH:MM:SS is
  preferred.


I would like this url with this parameter values to work: http://example.com/api/?start=20161101&amp;end=20161102

I thought it was working at first, but apparently not when I get my results.

This works: 

http://example.com/api/?start=2016-12-08%2000%3A00%3A00&amp;end=2016-12-21%2024%3A00%3A00


I am trying to have those clean parameters instead. How can I change the filter format to use the YYYYMMDD format? I don't want to change my field type because it is storing the time for my events. I want to get the data through only dates.
You need to:
 - Set the filter granularity to "Day"
 - Add a date format "Ymd" admin/config/regional/date-time/formats
 - Add a date type to attach that to...admin/config/regional/date-time
 - OR, just change whatever date type the view is using to use it
