Time Server Example -- Error in documentation

[Maverick.Crank.GRey]

Hello Trustin,

Since it will make the example a little bit longer than I expected, I'd like

Okay. But I would like to use seconds.
2208988800L seconds = (70 * 365 + 17) * 24 * 60 * 60
70 years
365 days in regular year
17 additional days in leap years
24 hours in day
60 minutes in hour
60 seconds in minute

As a result we have the following code in the method.

@Override
public void channelConnected(ChannelHandlerContext ctx, ChannelStateEvent e)
{
    Channel ch = e.getChannel();

    ChannelBuffer time = ChannelBuffers.buffer(4);
    time.writeInt((int) (System.currentTimeMillis()/1000L + 2208988800L));
    ChannelFuture f = ch.write(time);

    f.addListener(ChannelFutureListener.CLOSE);
}

It is simple. Since we are running our TimeServer something like
----
// to open ports lower 1024 on Unix-like systems you must be a root
bootstrap.bind(new InetSocketAddress(8037));
----
we can ask rdate use this port (8037) opened on our local interface
(localhost):
----
rdate -o 8037 -p localhost

 -o 8037 - Use port 8037 instead of port 37.
 -p - Do not set, just print the remote time.
 localhost - connect to the local host.
----

I hope it will be enough.
