Interesting that this has a 180 day "make available" but the other stuff 
in the EO (PNT profiles, etc) is years down the road.

As a practical matter, this has already been done. WWV, WWVH, and WWVB 
all provide coordinated universal time without GNSS.  The EO says 
nothing about accuracy, precision or availability.  In fact, the dial up 
service 
(https://www.nist.gov/pml/time-and-frequency-division/radio-stations/wwv/telephone-time-day-service) 
would also work.
