I am having sudden problems on my system with a Sure GPS with PPS. I am running chrony, using a serial port to bring in the PPS signal. Everything was working well-- the rms timing on the pulse was about 1usec. Suddenly on Nov 18 at very close to 00:00:00UTC the timing went to hell, and the rpms is now at 20us-- the individual pulses have an offset that fluctuates between about 50us, and -50us. Is there any hint as to what I could do to track down the problem. Could it be the sattelites (ie the timing has suddenly gone from ns to tens of usec for some reason? But if this were true I would have expected to hear many many loud screams here.) Or the gps receiver? (again, unlikely I would think). Or the serial card? or chrony? Or the computer clock? (the computer was not rebooted anywhere around that date). : By the way, what in the world has happened to this newsgroup? I am getting about 1 valid message to over 100 Case Solutions?
