I think that is generally true. > Anyway, the effect I am seeing is also very slowly drifting, see screenshot > of about 20 days of data below. Your pictures are not making it to the list, it seems the list server strips out inline images. Actually inline images would imply you are probably sending HTML messages and they are getting converted to plain text. You could try attaching the image as an attachment to a plain text message, that may get through to the list. Regarding the drifting, if you mean relative to the wall clock time, GPS to planet alignment shifts because of rotation of earth, so the GPS effects tend to align to around 23 hours, not 24 hours. Is that the drift you are seeing, or more than about an hour per day relative to solar time? -- Chris Caudle _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
