Hi Folks--

I've updated the shm driver for linux parallel port pps to support
the nanosecond timestamp via clock_gettime. The version has been
added to my web page as shm-ns.c:


It's worked for a day now so it must be ready for release. Cough.

My test system was Gentoo running  linux 3.18.3 with glibc (Gentoo
2.20-r1 p3). BTW its cool to see the extra resolution bits reported
via ntpq -c rv in the "offset" field. My test system has routinely
been reporting offsets less than a microsecond:


If you have comments, bug reports, patches, well they are appreciated.

Yours for happy chiming--
