Says who? Didn't we just burn a lot of calories discussing whether
UTC was a real number or a continuous function? Time does not end at
midnight, rather, a time without a date or a date without a time are
incomplete. Are we to believe that there is something evil about
expressing negative time values, too? Just depends on the epoch.

Put it in angle notation. 12 hours UT = 180 degrees = pi radians,
but also = -180 degrees or -pi radians. So what?

Would think the usual tactics apply: interpret rules as loosely as
possible on input and as strictly as possible on output.
