It is evident from: http://gentoo-wiki.com/HOWTO_NTP that this is a known
problem.
Basically, NTP v4.2.x doesn't support multiple restrict lines. Therefore, when
the default /usr/share/ntp/ntp.conf is copied to /etc/ntp.conf, it doesn't work
because "restrict default notrust nomodify" and "restrict 127.0.0.1" need to be
combined into "restrict 127.0.0.1 notrust nomodify".
Without performing the above correction, when one types "ntpq -np", the jitter
is set to 4000 and the output looks something like:
remote refid st t when poll reach delay offset jitter
===================================================
tock.usno.navy 0.0.0.0 16 u - 64 0 0.000 0.000 4000.00
Reproducible: Always
Steps to Reproduce:
1. emerge ntp
2. cp /usr/share/ntp/ntp.conf
3. /etc/init.d/ntpd start
Actual Results:
remote refid st t when poll reach delay offset jitter
===================================================
tock.usno.navy 0.0.0.0 16 u - 64 0 0.000 0.000 4000.00
Expected Results:
4000 should be closer to 0!
This is only a minor issue - although it does waste time!
