I have an interesting not really problem, but mystery. I have 2 Debian Etch machines set up with Garmin 18 GPSs and PPS (Debian1-PPS and Debian2-PPS). I have 2 other Debian Etch machines which have no PPS source directly attached to them (Debian3-NOPPS and Debian4-NOPPS). The Debian1-PPS and Debian2-PPS use their own PPS source, and each other's PPS source, among other servers. Debian3-NOPPS and Debian4-NOPPS use both the Debian1-PPS and Debian2-PPS, among other servers. On Debian1-PPS the offset for the Debian2-PPS time is in about 4 us, and vice versa. On the NOPPS machines, the offsets for the PPS servers are 1-2 ms, and within us of each other.
So, it seems if a machine has a PPS source, other PPS sources used by that machine will have much lower offsets than machines with no PPS source. Is this a fluke? We can try to solve this mystery, hopefully for better timekeeping for everyone.
