  The network time server developed by Beijing Zhongxinchuang Technology Co., Ltd. DNTS-7 is a high‑tech, intelligent, stand‑alone time server based on the NTP/SNTP protocols. It obtains standard clock signals from GPS geostationary satellites and disseminates this information across the network, enabling devices that require precise timing—such as computers and controllers—to synchronize with the standard clock. Standard clock data is transmitted over TCP/IP networks, and DNTS-7 supports multiple popular time‑distribution protocols, including NTP and time/UDP, as well as custom‑defined time‑broadcast packets with configurable UDP ports. The port numbers for NTP and time/UDP are fixed at 123 and 37, respectively, as specified in RFC‑123 and RFC‑37. Additionally, DNTS‑7 supports the broadcast mode of the SNTP protocol.
