I quote from /usr/share/doc/ntp/README.Debian.gz:
If DHCP is used to configure the host, and the DHCP server sends
information about NTP servers, then this information will be used
automatically. This is done by making a copy of /etc/ntp.conf at
/etc/ntp.conf.dhcp, replacing the server entries with the information
provided by the DHCP server, and restarting the NTP server.
In order for this to work, the "ntp-servers" option must be mentioned
in the "request" statement in /etc/dhcp3/dhclient.conf. This is not
the case in a default installation. A complete configuration might
look like this, for example:
request subnet-mask, broadcast-address, time-offset, routers,
domain-name, domain-name-servers, host-name,
netbios-name-servers, netbios-scope, interface-mtu,
If you don't like using the NTP servers sent by the DHCP server, this
is also the right place to turn off this behavior.
