In many applications, it is more important that all devices within some environment agree upon the same standard time, than that this standard time is within a small offset of true atomic time. This has been discussed before here, but you don't seem to get it. He may well want all his computers to be within a millisecond of the same time reference, but may not at all care what that reference is. There are many applications where this is a reasonable expectation. Suggesting a Garmin GPS to be added to each and every configuration brought up by someone is really not adding much. When it is not there, it is not there. And the configuration may still be very useful. _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
