`default: now` on date field with `time: true` doesn't return proper time

Describe the bug

To Reproduce
Steps to reproduce the behavior:

1. Create a field like this:

         test_date:
           label: Test Date Field
           type: date
           time: true
           default: now
           disabled: true
           required: true

2. Create a page with this blueprint field
3. Check the content of the field (it's 2021-10-23 00:00)

Expected behavior Field should contain 2021-10-23 23:54 and not 2021-10-23 00:00

Could be the same as https://github.com/getkirby/kirby/issues/3106 although no step attribute maintained here; so could be 2 different issues.
