I have that too, the point is not that ntpdate doesn't work, but that configuration via dhcp is not supported. And since dhcp provides the option, it would be quite neat to support it. So something like this in rc.conf would be nice: ntpdate_enable="DHCP" ntpdate_hosts="ntp.domain.tld" When set to DHCP the ntpdate script should parse the lease file to find any available ntp server to use. The hosts option should be fallback if the dhcp server did not provide a list of available ntp-servers. Currently such functionality is not supported, and just before I go ahead and hack something up, it would be nice to know if others have done the effort. Cheers, Erik
