Zhongxin Chuangwei provides a precision clock to the People’s Bank of China.

Recently, the People’s Bank of China issued a request for time‑server equipment. Beijing Zhongxin Chuang Co., Ltd. proactively collaborated to develop a detailed proposal and recommended its self‑developed and manufactured DNTS‑8 model as the bid‑eligible product. Following a fiercely competitive bidding process, Zhongxin Chuang stood out thanks to its high‑quality products and comprehensive after‑sales service, ultimately securing the contract for the People’s Bank of China’s time‑synchronization project.

The People's Bank of China (English abbreviation: PBOC ), abbreviated as the central bank, is People's Republic of China of Central bank , People's Republic of China State Council constituent departments . In State Council Under the leadership, formulate and implement Monetary policy , prevention and resolution Financial risk , maintenance Financial stability 。

People's Bank of China Developed independently by Zhongxin Chuang Type DNTS-8 The time server underwent rigorous testing, and the results consistently exceeded the specified performance parameters. We were highly satisfied with both the product quality and the after-sales service, and proceeded to place an order and put it into operation without a hitch.

The DNTS-8 time server, developed by Beijing Zhongxinchuang Technology Co., Ltd., is a high-tech, intelligent, stand-alone clock synchronization server that operates based on the NTP/SNTP protocols and delivers high precision. The DNTS-8 time server acquires standard clock signal information from GPS or BeiDou geostationary satellites and transmits this information across the network, enabling devices requiring time signals—such as computers and controllers—to synchronize with the standard clock. When both GPS and BeiDou receivers are in use, a priority can be defined; by default, BeiDou takes precedence, with GPS serving as a backup. If neither receiver receives a signal, the DNTS-84-RGB relies on its built-in rubidium atomic clock for timekeeping, achieving a timing accuracy of up to 1E-9. The DNTS-8 disseminates standard clock information via TCP/IP networks and supports multiple popular time‑broadcasting protocols, including NTP and time/UDP, as well as custom time‑broadcast packets with configurable UDP ports defined by Zhongxinchuang Technology. The port numbers for NTP and time/UDP are fixed at 123 and 37, respectively, as specified in RFC-123 and RFC-37. Additionally, the DNTS-8 supports the broadcast mode of the SNTP protocol.
