Thanks for clarifying that, Richard. I was concerned that the OP might have thought that +/-10ms was easily achievable with Windows over the Internet. BTW: Windows Vista and Windows 7 now have clocks running at a 1KHz rate, with a quantisation of less than 1 ms. My /best/ Windows/GPS PC keeps within about 200us, but it's rather temperature dependent. I use MRTG to monitor it: http://www.satsignal.eu/mrtg/feenix_ntp_2.html http://www.satsignal.eu/ntp/NTPandMRTG.html Cheers, David _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
