If I had a life-or-death application depending on NTP, I'd do what I've already suggested: Use GPS and multiple stratum-1 servers, and clip adjustment delta magnitude. I might also listen for a heartbeat (no pun intended) saying "device agrees with NTP server", then raise an error if that condition failed. BD> Sending bad NTP values could in theory be responsible for killing BD> someone's scratch monkey... I can only hope that my life is never entrusted to a device that, at the suggestion of a lone NTP server, would adjust the clock by 42 years. IANAL, nor do I play one on TV, but such a setup would seem grossly negligent. Automated devices fail. Pretending otherwise is foolish. But you _did_ say "scratch monkey". :-) Eddy -- Everquick Internet - http://www.everquick.net/ A division of Brotsman & Dreger, Inc. - http://www.brotsman.com/ Bandwidth, consulting, e-commerce, hosting, and network building Phone: +1 785 865 5885 Lawrence and [inter]national Phone: +1 316 794 8922 Wichita ________________________________________________________________________ DO NOT send mail to the following addresses: [email protected] -*- [email protected] -*- [email protected] Sending mail to spambait addresses is a great way to get blocked.
