When you discipline signals and clocks the way it's done in a GPS receiver you can save yourself quite a bit of code for keeping proper track of the sign by choosing a clock which is always on the low (or if you prefer: high) side of the ideal. Given that the spikes in the (corrected) PPS on the Oncore UT were related to just such a sign bug, I'm not surprised Motorola did this for the M12 family. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [EMAIL PROTECTED] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
