We actually added a time-change-notification mechanism internally a long
time ago but never saw demand for it and so never bothered trying to
push it upstream.  Ours is signal-based.

Among other things we use it to pass on time-change notifications to an
emulator running a proprietary OS that really cares about having an
accurate time-of-day but can't afford a syscall to retrieve it every time.
