I've now got the Garmin GPS 18 plugged in to my time server at 81.174.173.221, and my current offset is now no more than 0.010 ms, with a jitter of around 0.001. I'm also connected to a few goodish internet servers coming in on an asymmetrical 2Mb/288Kb adsl line.
Clearly I need to fudge a time offset for the gps, corresponding to mean hardware and os delays. My goodish servers are showing offsets of between -6ms -- +4ms and it is unclear which one I should choose as a base: this approach may not even be sensible. It may well be that I must be content with accuracy of around the ms level, even though the gps is potentially 100 times more accurate. This must be a common problem. Where do I go from here? -- Richard A Leach _______________________________________________ timekeepers mailing list [email protected] https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers
