> In short, the GPS to UTC time correction polynomial got screwed up. Yes, that was an exciting time!
---- For newcomers to the list, the bizarre GPS 13 microsecond jump was a hot topic on time-nuts back in 26-Jan-2016. The thread starts with an observation by Paul Boven: https://www.febo.com/pipermail/time-nuts/2016-January/095667.html And includes detailed follow-up by Martin Burnicki: https://www.febo.com/pipermail/time-nuts/2016-January/095692.html https://www.febo.com/pipermail/time-nuts/2016-January/095756.html https://www.febo.com/pipermail/time-nuts/2016-January/095714.html https://www.febo.com/pipermail/time-nuts/2016-January/095753.html If you have time, read the full "GPS jumps of -13.7 us?" thread from the archives: https://www.febo.com/pipermail/time-nuts/2016-January/subject.html#95667 And also the "GPS PRN 32" thread: https://www.febo.com/pipermail/time-nuts/2016-January/subject.html#95682 ---- As far as monitoring mains phase -- a 13 microsecond step would be lost in the normal jitter and drift of power line timing. My 60 Hz logging was unaffected by the event because I use a cesium reference (not GPS or GPSDO). /tvb _______________________________________________ time-nuts mailing list -- firstname.lastname@example.org To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
