Remember to cover the basics, that is, what you expected to happen and
what in fact did happen. You don't know how to make a good report? See

file org-plain-date-to-date-time.org has:

* plain date
C-c ! gives:
[2023-02-21 Tue]
* updating plain date
C-c ! followed by C-u C-! gives:
[2023-02-21 Tue 00:00]
* date-time
C-u C-c ! gives:
[2023-02-21 Tue 14:13]

I expected that updating an existing date with C-u C-c ! would produce
the same result as creating a new date-time.
