According to a document I just found (<http://tf.boulder.nist.gov/general/pdf/1743.pdf>) it would seem that the naval transmitters are at least .05 10e-9. I don't imagine they have gotten worse since that was published (1967!).
So maybe not quite as good as WWVB (which was then spec'ed at .02 10e-9) but probably still useful. But no time code of course. The least common multiple of the two is also 120 khz. Food for thought.
