Resetting System.Threading.Timer using .Change

Could someone please clarify the correct usage for System.Threading.Timer please.

I have a Server Client acknowledgement response model. What I am aiming to do is resend logged messages from the server, if no acknowledgment is received in after a set period of time.

So when the first message is sent I store a Timer;

AutoResetEvent autoEvent = new AutoResetEvent(false);
TestsTimeout timeout = new TestsTimeout(firstTest, _socket);

TimerCallback resendCallback = timeout.ResendMessage;
Timer timeoutTimer = new Timer(resendCallback, autoEvent, timeoutPeriod, timeoutPeriod);

Then when a acknowledgement to a message is received I simply want to reset the time back and send the next message out. 

timeout.Change(0, timeoutPeriod);

Now, I followed the MSDN example for this, however, 0 seems to invoke the callback straight away? is this correct? what is the corect way of doing this please?

Specify zero (0) to restart the timer immediately.

There you go.
