我们生活中感知的事件(Event)发生的先后是依赖于时钟的,而分布式系统“A distributed system consists of a collection of distinct processes which are spatially separated, and which communicate with one another by exchanging messages.”中很难包含一个实际的时钟(Wall Clock),同时在多个不同process中的时钟往往...
由于石英钟漂移,误差会逐渐积累,造成时钟偏移Clock skew(在一个时间点上,两个时钟之间的差)。最常见解决方案的是使用网络时间协议(Network Time Protocol,NTP),定期从拥有更精确时间源的服务器(原子钟或GPS接收器)获取当前时间。所有主流操作系统都有内置的NTP客户端。 由于随机网络延迟,时间同步是很困难的。网络延迟...

But in the future, when new types of clocks will be built based on different construction material and functioning principle, the correction of the GPS clocks would be different. In order to make the distinction between ``clock'' and ``time'', we suggest a Experiment # 1 with different ...
In a time clock a single straight line of time printing elements 52 (Fig. 2, not shown) is advanced by a clock mechanism and prints two times in offset positions on a card inserted in a guide 32 at different times but in the same position within the guide by different positioning of ...
