* Frank Kardel was the one to point my nose at NTP. He also wrote that
  fine DCF77 driver (among many others).

* Dave Mills had to read a lot of my stupid questions and bug reports
  about NTP and PPS support.

* Harlan Stenn volunteered to integrate my Linux patches in xntpd. He
  also made the package more widely accepted by converting the
  Makefile-mess to GNU autoconf.

* Theodore Y. Ts'o finally told me where to start adding PPS support
  to the driver.  His very first patch made me start the project.

* H. Peter Anvin ported my original patch forth to Linux 2.1, and
  he'll probably do it again...

* Harald König gave several useful hints and supplied his patches.

* Bill Broadley for trying out all the patches.

* Nigel Metheringham supplied an updated patch for sparc architecture
  and Linux-2.0.33.
