given that you trust the US-government (well, ...) you might use your own s=
tratum 1 server using a Raspberry Pi with GPS.
here is a well done how-to:
http://open.konspyre.org/blog/2012/10/18/raspberry-pi-time-server/
I still need some spare time to get it running, all parts are here, but wit=
hin my office location I have a bad GPS signal reception, so I have to do i=
t at home.
So build your own stratum 1 server (maybe a second one with DCF77 or whatev=
er you can use for redundancy), off from these servers build 2 or more stra=
tum 2 timeservers for redistribution to offload your stratum 1 servers.
http://clepsydratime.com/Products/Time-Server-NTS3000 is a cool alternative=
. They are located in Poland, IIRC. And this box sells for less than 2,000 =
euros (this price is 2 years old). And it gives you GPS (USA), Glonass (Rus=
sia) and DCF77 (land based).
One of the best Timeservers are sold by meinberg.de
just my 2 euro-cents.
