"flag3 1" is equal to "HARDPPS" in /etc/ntp.oncore.0

it works:-) both in kernel HARDPPS and when PPS is handled from ntpd.
OnCore does use PPS to timestamp each message, which comes from serial
port -- without this there would be VERY poor accuracy from only serial
when you use ONCORE and ATOM, ONCORE as preffered peer tells NTPD when
to turn on/off kernel hardpps.
