With the swift development of computer network, the network application is very common now, and network systems in multitudinous domains, such as the electric power, the petrofactionchenical, the finance industry (stock,bank), the broadcast and television industry (broadcast, television), the transportation industry (train, airplane) and so on need to maintain the computer''''''''s time synchronization and time accuracy at wide range. Therefore, a good time generator is extremely essential. In order to adapt these domains''''''''request of more and more precise time, Silimin Company has independently developed the SNTS network timing server on the basis of SGPS series product. Besides inherits all functions of the satellite synchronization clock, embeds the international popular NTP-SERVER service, provides the precise time proofreading service to each network equipment by the NTP agreement, and it is independent to other network systems that may directly access the network as the network timing server. In addition, it has many kinds of time correction ways and easy to operate.
