It can take a few minutes of ntpd running before you get the + and *
marks in the "remote" column, like Stan has.  I don't remember exactly
what they mean, but it's something along the lines of your ntp daemon
having established a "link" with those remote ntp servers.  I'm not sure
if that accounts for all the zeros in the other columns, though.
