My ntp.conf looks like this:

# General Configuration
server 0.us.pool.ntp.org
server 1.us.pool.ntp.org
server 2.us.pool.ntp.org
server 3.us.pool.ntp.org

# Drift file
driftfile /var/db/ntpd.drift

The output from ntpq for the BSD 7 system is this:

     remote           refid      st t when poll reach   delay   offset  jitter

and the output from the BSD 8 system is this:

The most obvious difference is the .INIT. entries, but there also appear to be several "0.0" type of entries that look suspicious. What do these imply?
