I'm not sure if anyone is working on support for HW timestamping in ntp. With chrony, you can test it with an experimental code in the hwts branch of https://github.com/mlichvar/chrony. $ ./configure --enable-debug && make # ./chronyd -d -d 'hwtimestamp *' 'server pool.ntp.org iburst' |& grep TIMESTAMP TX SCM_TIMESTAMPING: swts=1493285228.512531924 hwts=0.000000000 TX SCM_TIMESTAMPING: swts=0.000000000 hwts=1493285226.073103885 SCM_TIMESTAMPING_PKTINFO: if=2 len=90 RX SCM_TIMESTAMPING: swts=1493285228.530657351 hwts=1493285226.091054104 TX SCM_TIMESTAMPING: swts=1493285230.553457791 hwts=0.000000000 TX SCM_TIMESTAMPING: swts=0.000000000 hwts=1493285228.113705104 SCM_TIMESTAMPING_PKTINFO: if=2 len=90 RX SCM_TIMESTAMPING: swts=1493285230.582817079 hwts=1493285228.142890229 -- Miroslav Lichvar
