They could put the new station on 60 kHz as well. If they can't get

decade ago.


Joke's on them. GPS time is implemented by the atomic clocks in the
GPS ground control stations and the GPS satellites themselves. Since
it is not updated with leap seconds, GPS is currently ahead of UTC by
14 seconds.

FWIW, the time obtainable from LORAN-C transmitter sites is an
additional 9 seconds ahead of that (23 seconds total), and the
international atomic time scale, called TAI for Temps Atomique
International and which is a statistical timescale based on a large
number of atomic clocks, is currently ahead of UTC by 33 seconds.
