Lars?
FWIW there is a similar pattern in the function iso8601--encode-time.
BTW I just noticed that decoded-time-set-defaults was mistakenly
announced in NEWS as encoded-time-set-defaults - should that be fixed on
emacs-27 or master?

The year doesn't matter, since my-mins-between cares only about the
relative difference between strings of the form "HH:mm", i.e. the hours
and minutes fields.
The other decoded time fields resulting from parsing don't matter, as
long as they are equivalent for both strings.
Thanks,
