[time-nuts] GPS timing receivers

It can, and does, sort of -- but you have to first tell
the Loran-C receiver what time it is before it knows
which pulse is aligned to the UTC 1 PPS pulse.

For example the 9940 GRI chain repeats every 497
seconds so you sync the Loran-C receiver on the
correct 497th second and it's now locked to a UTC
1 PPS until you power it off.
