Ah, but who do you trust? Trump, Putin, or Xi's clock?


That said, we use a Stratum2 clock for our AS, which syncs using GPS at
$dayjob. So... I guess we trust Trump's clock.


Perhaps there's a market for a device that takes GPS, GLONASS, and
Beidou, and references the three for sanity checks in the event of
$unforseen_circumstance. Assuming such a thing were possible - admittedly
I know little about GLONASS, and even less about Beidou.

I was casually (yes, really) looking around at some GNSS modules available
the other day, and readily found quite affordable ones that can receive at
least 2 at a time, of those systems.  GPS and GLONASS being the most
complete, so probably the best bang-for-the-buck.

I'm only an armchair time-nut, so I can't really speak to their precision
and such, so this is very much a FWIW post.

Who's authoritative for time? Even the national labs aren't --
UTC is figured well after the fact.


In the United States that would the United States Naval Observatory
(USNO) Master Clock (http://tycho.usno.navy.mil/).  You can read more
