I've built a few little time servers based on OpenBSD. The kernel can
grab a timestamp of the 1PPS signal and can extract time data from the
NMEA stream and feed those to ntpd. My home time server is a gps18/lvc
hanging off serial port 2 on a soekris net4801. it's adequate,
considering i have to use home powerline network to bring net to the
soekris. I'm sure there are are much higher precision installations,
but this was quick, easy, and basically good enough.

PHK's ntpns looks neat too...


GDB has a 'break' feature; why doesn't it have 'fix' too?
