Webb3. The Slave node takes a timestamp when it receives the «Sync» message (T2) • This timestamp is stored for further • No timestamp is taken when a FollowUp is received 4. The master repeats the sending of a «Sync» and optional «FollowUp» in a defined interval • Timestamps are taken on both sides again (T1’ & T2’ …) WebbFor the best precision, PTP uses hardware timestamping. NIC has its own clock, called Physical Hardware Clock (PHC), to read current time just a moment before the packet is sent to minimalize the delays added by the Kernel processing the packet. Not every NIC supports that feature. michigan victims school shooting
