Technically it's an easy fix (patch attached),
but it changes a long-standing behavior.

I wonder if it will break some existing scripts that might rely
on being 'midnight'? (even implicitly, because the user isn't aware of
this nuance).

For example, currently '2018-03-15 + 14 hours' is 2pm on March 15th.
With this change, it'll result in 2am on March 16th.

What do you think?
