Firstly, I got two threads confused, so some of my comments weren't
based on your situation. In particular, the unsynchronised DCF system
relates to the other t

I think your initial goal was synchronization to 10 microseconds.
Do you really need that for NFS? (Do file times include the fractions
of a second?)
Most interaction

If your master server has GPS, its time will be more stable.
That means your clients can sync to a stable clock rather than
trying to track a clock that is wobbling around. (Things
are simpler and work better when t
Has anyone written (or is anyone writing) an NTP reference clock
driver for the C--MAX CMMC-8P-MF radio clock module? The commands and
responses for this unit are detailed on their web page (http://www.c-

reference clock drivers,
