When the number of ticks reaches zero for a timer, it calls the timeout handler routine to handle the corresponding timeout for that connection.

当计时器的计时单元数达到零时，它将调用超时处理程序例程为该连接处理相应的超时。

Finally, we start a timer handler, as shown in Listing 6, to handle the scenario where the Web service client callback handler is never called, which will result in a timeout.

最后，我们启动了一个计时器处理程序(如清单6所示)来处理以下场景：Web服务客户机回调处理程序一直没有被调用，这将导致一个超时。
