I don't.

In a client, it doesn't _hurt_ as long as nobody asks the client
for the time.

In a server, it can keep the flock together even while the server

Some people may prefer to be explicitly unsynchronised, but for
myself I'm happy to accept that stratum 11 means we don't really
know what time it is - but wherever we go, we go there together.

The fatal flaw, of course, is that with a single package, client
and server will both revert to their _own_ local clock. That
defeats the purpose.
