Last time I looked it up, the National Bureau of Standards claimed that
time accuracy when TELEPHONING the WWV audio in Fort Collins, CO. was
"not better than 30 milliseconds".  It sounds to me like 12 seconds is
not telephone network delay.

Given a choice between WWV and the Naval Observatory, you should consider
WWV to be more accurate.

It would be interesting to find out why there's such a discrepancy.
