But it can still be <=, by being <.
I would personally be OK with just saying that (year, month, day)
sorts less than (year, month, day, ...) regardless of time, simply
because of the type -- but I admit that would be arbitrary.

Mea culpa.  I was mis-remembering, and thought that even this would
break because of sort stability.
