I think you will have a much better chance of getting Garmin to fix something if we can come up with a clear description of what is broken and/or a simple recipe for a setup that demonstrates the problem. What do you mean by "more than one second delayed"? That sounds like you are looking at the wrong PPS signal. Could you describe your test setup? I don't see a problem with a delay as long as it's reasonably stable. ntpd has fudge time1 to correct for that. (Even the old "working" firmware had a horrible delay.) Jitter would be a problem. What sort of range of delays are you seeing? Kiwi Geoff reported about 150 ms of jitter. That's ugly, but I think we can live with it. -- These are my opinions, not necessarily my employer's.
