Which is also why I find it amazing that on my gps controlled server, with a Regina level 1 backup, the regina offset is less than 1ms even though the round trip time is 40-50 ms. Ie, assymmetric router delays do NOT appear to be a problem. Just one data point however.. _______________________________________________ questions mailing list questions@lists.ntp.org https://lists.ntp.org/mailman/listinfo/questions
