【摘要】 介绍如何利用GPS接收器获取准确的UTC时间 ,在分布式实时操作系统QNX下 ,实现系统时间和UTC的一致。同时讨论了如何建立网络时间服务器 ,通过执行网络时间同步算法 ,实现局域网内不同计算机之间的时间同步。最后文章给出在具体应用中的实例更多还原

【Abstract】 This paper mainly discusses how to get accurate UTC time by means of GPS receiver,and how to realize the system time consistent with UTC under the distributed realtime OS QNX.At the same time, the way of building the LAN time server and implementing an algorithm for LAN time synchronization among a number of computers is described too.A detailed application example is given at the end.更多还原
