Yes, exactly. It depends entirely on your internet connection. As soon as you get even "slow" 10Mb/s fiber the distinction between LAN and Internet starts to melt away. The problem with Cable TV is that it is a shared connection with who knows how many others. Shared media have collisions with back off and retries and are not deterministic. I do have a local NTP server. I had one back in the days of dial-up phone modems and still have one with my current fiber connection. I was just pointing out that the local NTP server is less useful as the Internet connections get better. Every few years I get motivated to improve the NTP server. The next step is for certain going to be to use the ARM's PRUs somehow. That would remove the effect of the OS from timing which is now the largest source of error. > Cheers, > David > -- > SatSignal Software - Quality software written to your requirements > Web: http://www.satsignal.eu > Email: [email protected] > _______________________________________________ > 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. > -- 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.
