The code I'm using to collect PPS data is here: http://www.megapathdsl.net/~hmurray/time-nuts/60Hz/pps.py It only runs on Linux. It's only 100 lines of python. The UI is a text editor. I'll clean it up a bit and/or write a few lines of documentation if anybody needs it. It sould be straightforward to rewrite it to use the c API so it would run on *BSD. RFC 2783 has the background info. -- These are my opinions, not necessarily my employer's.
