Based on personal experience, this strongly suggests that you weren't married at the time :-).

I personally want all the clocks in my house, including all the computers (I have about 10 running at any given moment here), to have time resolution better than my ability to perceive errors. (To my eye that is about 100ms for clocks with a sweep second hand.) and in the 1ms-or-better range for the computers. I want to know that, when two things get time-stamped on different machines, I can tell which happened first from the point of view of a DBMS dealing with concurrency issues. So a stratum 1 server in my house that is independent of my external internet connectivity seems desirable. Look, I used to leave WWV running all the time on a receiver. That background DOOOO DOOOO DOOOO was very reassuring as I moved through the house watching the sweep second hands ticking in time with WWV. Time to move forward in true time-nut fashion. -- Brian Lloyd Lloyd Aviation 706 Flightline Drive Spring Branch, TX 78070 br...@lloyd.aero +1.210.802-8FLY (1.210.802-8359) _______________________________________________ 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. _______________________________________________ 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.
