Slaved to gps == use networking to keep their clocks.

OK.  That is indeed a good point.

Obviously GPS needs to provide quicker almanac sync.

But I have to ask:  why should navigation systems care about time of
day?  Shouldn't seconds since an epoch be enough?

It seems like the only issue is human monitoring of the systems' idea
of now.

My point is that the majority of systems which care about timing and
which can not get almanac data to correlate an interval since an epoch
with human time-of-day do not, in general, really need the latter.
