WebThe rms value reported by ptp4l once the slave has locked with the GM shows the root mean square of the time offset between the PHC and the GM clock. If ptp4l consistently reports rms lower than 100 ns, the PHC is synchronized. Like ptp4l, phc2sys reports the time offset between PHC and System Clock, which determines if the clocks are synchronized. WebThe linuxptp package includes the ptp4l and phc2sys programs for clock synchronization. The ptp4l program implements the PTP boundary clock and ordinary clock. With hardware time stamping, it is used to synchronize the PTP hardware clock to the master clock, and with software time stamping it synchronizes the system clock to the master clock.
