Dear All,
I work for a firm which requires clocks to be synchronised to quite a
high degree of accuracy.
We have an existing ntp-based infrastructure but want to improve on it
to the point where the bulk of our hosts are synchronised to single
digit microseconds of each other if possible. We have about 400 hosts in
production, spread across about 15 sites.

I appreciate these may appear to be silly questions with obvious
answers - I am grateful in advance for your patience, and any research
sources you may direct me to.
Many thanks,
Paul
Paul,
What OS are your hosts running? If it's Windows, millisecond, not
microsecond accuracy will be what you can get at best when syncing over
the network.
If you really need microsecond, I suspect you will be looking at a GPS
receiver or two at each site, and distributing the PPS (pulse per second)
signal to each host, and praying that the hosts have a serial port
connection!
Cheers,
David
