# LinuxPTP configuration file for synchronizing the system clock to

# a remote PTP master in slave-only mode.

#

# By default synchronize time in slave-only mode using UDP and hardware time

# stamps on eth0. If the difference to master is >1.0 second correct by

# stepping the clock instead of adjusting the frequency.

#

# If you change the configuration don't forget to update the phc2sys

# parameters accordingly in linuxptp-system-clock.service (systemd)

# or the linuxptp SysV init script.
