We would like a standaloine device that can serve as an ntp time source.
A known device is Sprectracom's Netclock 9489 (appx $3600).
Is there a similar device that is cheaper?
The netclock will provide time to a private LAN that is NOT connected to any other LAN (or the internet).
We could use a linux/Windows box with dual NIC's and have that box grab the time on the internet side and provide ntp to the private LAN side.
However, we would prefer a standalone device that is not connected to any other network.
