ntp servers

NTP is option 42, option 4 is for the older time protocol.

But the DHCP clients need to be configured to request/use that option.
This is usually the case on Linux, but on Windows if the client is a
member of Active Directory it will use the Domain Controller for time
sync. Supposedly if a Windows machine is not a member of AD it will
use option 42, but I've never seen that work. From what I've seen on
OS X setting NTP via DHCP isn't supported.
