Comment 2 for bug 74164

The fix for this, and obvious intended behaviour is:

 - add 'ntp-servers' to the 'request' directive in /etc/dhcpd3/dhclient.conf
 - add 'default ntp-servers 91.189.94.4' (ntp.ubuntu.com) to /etc/dhcpd3/dhclient.conf

I confirm that where the DHCP server doesn't pass the 'ntp-servers' option, the default is used and written to /etc/ntp.conf.dhcp, which is then used by ntpd (and otherwise).

It would clearly be more ideal to use 'ntp.ubuntu.com' rather than it's IP address, but it is the lesser of the two evils, since firewalls may prevent contacting external NTP servers, causing clock drift and subsequent NFS issues (eg with 'make'). For this reason, I request that this report is escalated to a bug, rather than wishlist.

This is readily reproducible with Ubuntu 8.04 HH with stock installation, and dhcp3-client 3.0.6.dfsg-1ubuntu9.
