date -s "2023-06-14 14:23:00"
sudo phc2sys -m -s CLOCK_REALTIME -c eth0 -w

The client device.

#Set the system time of the slave device to be one month later than the master device.
date -s "2023-05-14 14:23:00"
sudo ptp4l -i eth0 -m -H -s

Result confirmation

#Use the following command to view the system time of the master and slave devices. If the system time of the slave device is found to be the same as the master device, it indicates successful synchronization.
