Hi Riccardo,

you could use
ntpdate -qu ip.of.client.pc
to query the ntpd running on the client and check if the offset and stratum 
level is OK. Or you could include the clients in your server's ntpd.conf like this:

server ip.of.client.no1 noselect
server ip.of.client.no2 noselect
server ip.of.client.no3 noselect

(practical only if you do not have too many clients). Then you would see their 
synchronization status in your ntpq -p billboard.
