由于每次调用程序时的时间值是不同的，因此对于不同的调用，代码打印的值不同。

Because the value of time is different each time the program is invoked, the code prints different values for separate invocations.

我们看到这里，好的，我们想要，运行到程序的中段，打印出这些中间值，然后看看它能给我们什么信息。

We're going to come here. Well, let's, you know, we want to go somewhere halfway through the program, print some intermediate value that will give us some information.

请记住，尽管示例程序的所有工作只是打印节点名称、类型，以及可能的值(依赖于节点类型)，您仍然会获得一个完整的Node对象。

Remember that while all the sample program did was print out a node's name, type, and possibly its value (depending on that type), you've still got a complete node object.
