例如，在那些以前的日子中我发现早期的样例策略不允许系统更新硬件时钟(最后我提交了一个补丁以解决这一问题)。

For example, I found in those early days that the early sample policy didn't let the system update the hardware clock (I ended up submitting a patch to fix this).

最后，我将配合ca时钟更新图像来动画图像。

Finally, I animate the image by updating it in tandem with the tick of the CA clock.

图4显示了结果：不需要用户干预，每隔一秒钟进行更新的时钟。

Figure 4 shows the result: a clock that updates at one-second intervals without requiring user interaction.
