It will follow the normal transient response, which has a first zero crossing which I believe is at about 39 minutes for phase (RFC 1305) and rather longer for frequency). I'm not sure, but it may well overshoot by more than 5ms, in which it could take rather longer to be acceptable to the OP. It should get nowhere near being slew rate limited, so the 500ppm limit is academic. > Maybe it is best to set the clock initiallly so that it is out by by more > than 128ms (Eg advance it by 10 sec) and then use -g. That would be my best trick, but if you have to use -g, you probably don't know the time well enough to be sure that adding 10 seconds won't actually put it in the 128ms band! _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
