Abstract: A kind of offline clock synchronization algorithm is promoted based on the character of clock behavior and the cause and pattern of inaccuracy, with performance analysis provided. It can keep good precision, but no need of synchronizing momently with base clock. Repeat experiments in common PC indicate that the algorithm can keep precision in 40 ms.

Key words: clock synchronization, offline, clock behavior

摘要： 通过研究普通时钟行为特点，分析时钟误差产生的原因和规律，提出了一种离线时钟同步算法，并对其性能进行了分析。与以往的同步算法相比，该算法的优点在于可脱离基准时钟源，无须依靠网络同步，并能保持较高的精度。在普通个人计算机上的重复实验表明，精度可提高3个数量级，24 h误差控制在40 ms以内。
