摘　　要：在气象信息网络系统内,由于网络传输的延迟以及Internet传输的不安全性,导致时间的准确性难以保证,严重影响了气象报文传输的及时性和有效性。为了解决这一问题,基于NTP协议,采用client/server方式实现了系统内计算机和外部精确时钟源的主动对时,保证了系统内时间的准确性和一致性。In the meteorological network system,because of the network transmission and the insecurity of Internet transmission,it is difficult to ensure the accuracy of the time;and it affects seriously the timeliness and effectiveness of the meteorological messages.In order to ensure that all the computers time is accurate and consistent in the meteorological network system,we apply the means of client/server based on NTP protocol and realize computers in the system setting time to external accurate clock source.

关 键 词：NTP协议 客户端/服务器方式 对时
