Abstract: A first event occurs at a first computer at a first time, as measured by a local clock. A second event is initiated at a second computer by sending a message that includes the first time. The second event occurs at a second time, as measured by a local clock. Because of clock error, the first time is later than the second time. Based on the first time being later than the second time, an alternate second time, that is based on the first time, is used as the time of the second event. When a third system determines the order of the two events, the first time is obtained from the first computer, and the alternate second time is obtained from the second computer, and the order of the events is determined based on a comparison of the two times.

Abstract translation: 第一次事件在第一次计算机发生时，由本地时钟测量。 通过发送包含第一次的消息在第二计算机上发起第二个事件。 第二个事件发生在第二时间，由本地时钟测量。 由于时钟错误，第一次晚于第二次。 基于第一次晚于第二次，基于第一次的另外的第二次被用作第二次事件的时间。 当第三系统确定两个事件的顺序时，从第一计算机获得第一次，并且从第二计算机获得交替的第二次，并且基于两次的比较来确定事件的顺序 。
