You may want to explore other synchronization options such as IRIG, distributed PPS, or a distributed 10MHz clock. >I don't care if the synchronisation to the public NTP is accurate >around half a second. You're displaying a common misconception about NTP. The goal of NTP is not explictly to synchronize clocks to "the one true time". Rather, NTP synchronizes clocks to a common time base. A "better" time base, and a "better" distribution method, allows tighter synchronization between nodes. It so happens that UTC (via GPS or HF Radio or UDP) is a ubiquitous, stable, and relatively inexpensive time base. A side effect of using UTC as your time base is that your clocks are synchronized to the correct time. -- Steve Kostecke <[EMAIL PROTECTED]> NTP Public Services Project - http://support.ntp.org/ _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
