But most ntp setups use a daemon, which creates a security risk.

The 'netdate' utility allows you to synchronize against multiple time
servers, allows you to weight the responses, and doesn't run as a daemon
(thus it doesn't pose a security threat).

The downside to netdate is that it requires that port 37 is open on the time
server.  (Then again, ntp suffers the same 'problem', since your time server
has to accept requests on port 123 for ntp to work.)

Given a choice of both, I'd use netdate on time clients and ntp on time
servers.
