So your setup is this? 1. GM using SW time stamping 2. Slave 1 using SW time stamping 3. Slave 2 using HW time stamping Can you please post your setting, ie config file and command lines for both ptp4l and phc2sys on each host? Also, please post the log files. > I don't need an absolute synchronization, I just need that the few devices > are accurately in sync with each other. Putting aside the UTC issue, you will get better results by using HW time stamping on the master by configuring #3 as GM.
