My ISP's ntp server (in the UK) was taking a US clock as its sync source,
and as it has an asymmetrical path to the US, it was 20msec off.  Good
marks for effort but poor marks for achievement!

ntp.apple.com is on the wrong continent for me - do you know if direct
connections to the European versions are allowed?  The Eurpoean ones look
in good sync, although about 3msec out from the US server.

time.windows.com does not respond to an ntpq -p request, so I won't trust
