??? It is AFAIU used whenever display-time-mode shows the time when
display-time-day-and-date is non-nil.  Where this is shown doesn't
matter, and by default this is shown on the mode line.  Thus "makes no
sense" sounds somewhat harsh to me.

But feel free to change the face definition as you see fit.
