[Linuxptp-users] Clock jumped forward or running faster than expected

[Jord P. <jor...@ou...>]

Hi,

I have a server which synchronizes to a local NTP server in my network. Now I wanted to let phc2sys synchronize the physical hardware clock to the system clock (which is synchronized by NPT). The next step would be to run a ptp4l instance on the same machine to let it elect itself as the grandmaster node, distributing PTP time.

When launching a phc2sys instance where I try to synchronize the physical hardware clock to the system clock (# phc2sys -c eno1 -s CLOCK_REALTIME -w -m) it returns the message 'Clock jumped forward or running faster than expected'. After, the offset is very high and tries to slew itself down but this will take forever.

What could be the problem here or am I doing something wrong?
