Using prefer with the PPS is a hack. The real problem is to get the which-second info. Getting it from yourself (prefer-ing the local refclock) may work if your local time is set correctly, somehow, but it's not a clean long term solution. You can't get started if you don't have a GPS or external system to get close-enough and you can't detect or recover if somehow your system gets off by a second. (Think leap seconds with software bugs.) -- These are my opinions, not necessarily my employer's.
