摘　　要：针对现有基于广域网络的WEB浏览器时间精度不高、各终端设备的时间偏差大、时间保持能力低等问题,提出了一种基于WEB浏览器的时间管理方法。利用时差误差估计最小均方误差(Least Mean Square,LMS)算法,在广域网部署的终端上,实现了毫秒级的时间同步、时差监测、事件时标记录与查询等功能。研究结果表明,本研究可有效提高不同终端的时间一致性和准确度,具有高精度、高可用性和免维护性的特点。研究成果可应用于用户时间统一和时差检测。The Existing Web-browser based time service on wide area network has the technical problems of low timing accuracy,large time deviation of each device,low time keeping ability and inability to monitor the time deviation of each device.In this paper,a time management service based on web browser was proposed.Using the least mean square(LMS)algorithm of time difference error estimation,the functions of millisecond precision time synchronization,time difference monitoring,event time recording and querying were realized on the devices deployed in wide area network.The research results showed that this method could effectively improve the time consistency and accuracy of different devices,and had the characteristics of high precision,high availability and maintenance-free.The research results could be applied to user time unification and time difference detection.
