The goal is to discipline the internal software clock to GPS. A typical application is a database server that is running a web e-comerse site so that transactions get time tagged. So you would run a web, file or database server on a deterministic, no cache micro controller? Of course it would be easier to discipline a clock inside a purpose built computer but that does not server the gol of time tagging transactions in the server room Or to say in another way. If the goal is to deep a small micro processor's clock in sync with GPS you don't need anything as complex as NTP. What NTP does well is that it can use reference loves that are connected by slow and un-reliable data connections ilk the Internet. It works well over less than perfect links Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
