Re: http://www.pool.ntp.org/en/
With a vendor zone file the docs say 0.pool.ntp.org becomes
0.vendor.pool.ntp.org. Does this cascade to europe.vendor.pool.ntp.org and
ch.vendor.pool.ntp.org for example?

Hello everyone,

No. If you could, NTP could modify the local time to make the value zero.

NTP adjusts frequency, not time. It doesn't predict what the internal

Not addresses, but indexes. E.g. ntpq -c as -c
Angelo Mileto recently sent me some notes about determining the offset
of serial GPS data automatically using a Linux script. This value is
used as the time1 fudge factor. I hope you find it useful. My thanks

That's a good choice. These boxes are low-cost (but not yet multiple
