Public bug reported:
Today, I noticed that my laptop's time was ~4s ahead of my home NTP
server. Looking at 'ntpdc -sn localhost' I noticed that my laptop was
trying to sync with an unknown and unreachable server. Surprisingly,
this server was not in /etc/ntp.conf.
After some debugging, I found a stale /var/lib/ntp/ntp.conf.dhcp file
that was several days old. This explains why my clock drift so much as I
was not sync'ing with any reachable server.
