Hi! If being somewhat of a nitpicker, I would like to point out that as of 2007-04-01 will the MSF 60 kHz signal be transmitted from Anthorn rather than the traditional Rugby location. http://www.npl.co.uk/time/msf/ This will affect Table 9 on page 24 in draft-ietf-ntp-ntpv4-proto-04.txt. Cheers, Magnus
