Hi, I have know run a lot of tests. Just to let you know what I've got so far. I have tried NTP, and NTP + PTP (Precision Time Protocol). I haven't tried Chrony nor TSClock. I have used the software only implementation of PTP (ptpd).
With NTP only I have got an accuracy around 1ms, with one node synchronising to public NTP server, the others nodes synchronising to it with PTP I got 10 usec (between the nodes). I haven't used any hardware support (not GPS,PPS, for PTP). I might try the other solutions, if yeI do I'll send an email to complete the results. Anyway guys, thanks very much for all your answers, I have learned a lot.
