| | You may notice that there are only 5 seconds represented here - that's because in each timepulse there are two events, one for the rising edge, and then another for the falling edge, 100ms later. The i210 only reports both edges. |

| Part of the [[https://linuxptp.nwtime.org/about/|LinuxPTP]] project, [[https://linuxptp.nwtime.org/documentation/ts2phc/|ts2phc]] is a tool that synchronizes time stamps coming over the SDP with the PHC. The following command can be used to sync the incoming timestamps with the PHC. The system clock must be roughly correct for this to work correctly. | Part of the [[https://linuxptp.nwtime.org/about/|LinuxPTP]] project, [[https://linuxptp.nwtime.org/documentation/ts2phc/|ts2phc]] is a tool that synchronizes time stamps coming over the SDP with the PHC.
