Could you be more precise about what you mean? NTP synchronizes clocks.
There is no server or client, just clocks to be synchronized.
You can't serve time unless you have a reliable clock. In order to have
a reliable clock, you must have a local clock that's synchronized to a
So you can't be a server unless you're a client. Unless you have
something very unusual, like a reference clock that can tell you the correct
time at any instant.
You say you have an external clock that you read periodically. You want
to synchronize your local clock to that reference clock. That's what the
client code does -- probe a reference clock periodically and synchronize the
local clock to that stream of information.
Are you saying you don't want any of the networking code? You just want
to synchronize your local clock?
