Hello,
you have been waiting long for exciting news, but there are none. Any
way I released a maintenance release for PPSkit that fixes all known
problems. Specifically the PPS API is the old one, and the supported
ntpd is 4.0.92h (4.0.93 and 4.0.93a failed to work. I don't have newer
sources at home).
So what is PPSkit?

Title: PPSkit
Version: 0.7.1
Entered-date: 1999-08-15
Description: kernel time patch for NTP (RFC1305) and PPS support
(RFC1589)
against Linux 2.2.11 (kernel patch, documentation, test
programs). Implements nanoseconds as resolution.
Keywords: NTP, PPS, PPS API, kernel, RFC1305, RFC1589, xntp, time,
clock, pulse-per-second, synchronization, calibration,
adjtimex, nanoseconds, POSIX.4, nanokernel

And what is new?
NEWS for 0.7.1
+ Merged changes for Linux-2.2.11 and tested with proven configuration
(PPSkit-0.7.0 performed quite well). Modified ``adjtimex()'' in
kernel to clamp invalid values instead of rejecting them. This is
because ``ntpd'' does not care much about failing system calls, and
after very long thought I think avoiding the ``Ariane V'' failure
would not be bad.
+ Added a note about compilation problems and ``<sys/timex.h>'' (see
file ``BUGS''). Added a not about system include files and symbolic
links for glibc-2.1 in ``INSTALL''.
+ Updated ``enable_pps.c'' to compile with glibc-2.1 (glibc-2.1 uses
an ugly forward declaration of ``struct timeval''). Added version
of C library to compiled binary.
+ Fixed patch for ``ntpd/refclock.c'' to return success if PPS API was
set up correctly (Stupid bug found by David Schwartz).
Specific wish: people running nin-i386 architectures, please
contribute to the project!
Regards,
Ulrich Windl
