I do the latter. To use PTP to timestamp one would have to modify NTP source outside of refclock_phc(), which we would not presume to do. However the PHC loopstats has a standard deviation of 0.58 microseconds, so we are not far off in using standard NTP timestamping. Rich Schmidt > Do you

I have just written a PHC driver for NTP and tested it on this system: Supermicro SYS-50150EHF-D525 which has a pair of Intel 82574L NICs which have IEEE 1588 hardware-based timestamping. I'm using NTP dev 4.2.7p397 on Linux kernel 3.12 with linuxptp. One of the PHCs is sync'd via PTP to an FEI
