Can't change DateTime's format

[dimitriaatos]

I'm unable to make the admin ui display date and time in a format other than h:mm A do MMMM yyyy xxx. The following code is from the docs and it can be used to reproduce the issue.

const { DateTime } = require('@keystonejs/fields');

keystone.createList('User', {
  fields: {
    lastOnline: {
      type: DateTime,
      format: 'MM/DD/YYYY h:mm A',
      yearRangeFrom: 1901,
      yearRangeTo: 2018,
      yearPickerType: 'auto',
    },
  },
});
