Also I think, a computer that cannorttake a reboot has a problem wich needs to be adressed. Just my opinion, though..
2, I forgot to mention that I already do so, still takes too long to settle. I also don't understand what is taking so long, since - jitter or not - the nmea time is precise enough to just quickly set the time at startup and then let things go their way. Can someone explain that to me? Best regards, ../nico berndt _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
