Yes this is true. The server can be "very good", meaning that if it were better the clients that it servers could not "know" the difference. A simple is if a wall clock moved the hands with millisecond precision, it would not serve the clients (human eyeballs) any better if it moved with nanosecond precision because human perception is measured in mS not nS. Same with the time server, it communicates with its clients over a network that has someuncertainy in th delay and ultra-presision is lost. So nanosecond level timekeeping in the server is not required. You can do uSec level time keeping with the standard TTL can on most mother boards. However this list is for "nuts" and you might think it is fun to try and do 1000 times better time keeping than is needed, in that case you will need some kind of specialized clock hardware. Most nuts, I think would like to have a microsecond level wall clock even if it were pointless. -- Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
