The OP did not state a preferrence for TAI over UTC. The OP _did_ repeat the old misguided "all I care about is synchronization" meme about NTP. This is frequently uttered by people who want to operate a stable time island and want to have it for free. NTP needs a stable time base / frequency reference / what ever you want to call it to achieve the best possible clock stability. Without one your clocks are like a herd of kittens playing follow the leader. UTC is ubiquitous and cheap. A stand alone rubidium based PPS source will cost you at least $1K + the cost of integration. -- Steve Kostecke <[email protected]> NTP Public Services Project - http://support.ntp.org/ _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
