The clock synchronization server provided by the Xi’an Institute of Optics and Precision Mechanics, a joint venture between China and Singapore.

Recently, the Xi’an Institute of Optics and Precision Mechanics issued a request for a time server. Beijing Zhongxin Chuang Company responded proactively by preparing a detailed proposal and recommending its self-developed and manufactured DNTS‑9 model and digital sub‑clocks as the bid‑eligible products. Following a fiercely competitive bidding process, Zhongxin Chuang stood out thanks to its high‑quality offerings and comprehensive after‑sales service, ultimately securing the contract for the Xi’an Institute of Optics and Precision Mechanics’ time‑synchronization server project.

The Xi’an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences (abbreviated as XIOPM), was founded in 1962 and is one of the largest research institutes of the Chinese Academy of Sciences in Northwest China. Over more than fifty years of innovation, it has evolved into a comprehensive research institute that focuses on strategic high‑tech innovation and applied basic research.

The Xi’an Institute of Optics and Precision Mechanics conducted an in-depth evaluation of the DNTS‑9 time server, independently developed by Zhongxin Chuang. The results consistently exceeded the specified performance parameters, and the institute expressed high satisfaction with both the product’s quality and our after-sales service, leading to a successful procurement and deployment.

The DNTS-9 network time server, developed by Beijing Zhongxinchuang Technology Co., Ltd., is an intelligent, high-precision NTP network time server. The DNTS-9 obtains standard time information from navigation and positioning satellite systems such as GPS, BeiDou, GLONASS, and Galileo, and provides standard time services over the network via NTP/SNTP or other network protocols. Devices in the network that require time synchronization—such as personal computers, servers, and controllers—can synchronize with international standard time.

When used in conjunction with GNSS satellite receivers, priority can be configured; the system supports single‑receiver/dual‑receiver and single‑antenna/dual‑antenna configurations, with each receiver capable of operating in either standalone or combined timing modes. If both receivers and all other available time sources lose signal, the DNTS‑9 relies on its built-in temperature‑compensated crystal oscillator or rubidium atomic clock to maintain accurate timekeeping, while continuously providing time services to external users.

In addition to serving as a primary‑level network time‑synchronization device, the DNTS‑9 can also function as a secondary‑level time server, enabling more effective time synchronization in large‑scale network environments. It provides high‑precision standard time signals for systems such as distributed networks, computer security systems, file management systems, e‑commerce platforms, online B2B systems, and cloud database storage and maintenance. The DNTS‑9 has been successfully deployed across government, finance, mobile telecommunications, public security, petroleum, power, transportation, industrial, and defense sectors.

The DNTS-9 network time server is extremely easy to install and use: simply connect the satellite receiving antenna and plug the network port into a network switch, and you can achieve time synchronization across all devices on the network.

Client software

Provides NTP‑based time‑synchronization software for Windows, running as a service. Client support includes operating systems such as Windows 98, NT, 2000, XP, Vista, 7, 8, 10, and Server 2008, Server 2012, Server 2016, among others.

Centralized management software

Overview: The DNTS-Manager centralized management software not only enables easy remote network login, monitoring, management, configuration, and maintenance, but also allows real-time monitoring of time synchronization on both NTP servers and clients, supporting simultaneous monitoring of thousands of NTP servers and tens of thousands of client devices.

Client: request interval, deviation exceeding the threshold, request timeout, and so on.

NTP Server: Monitors NTP server information, including uptime, synchronization status, network parameters, satellite time, server time, and synchronization with the reference source.

Alerts: Alerts can be generated via protocols such as Syslog, SNMP, and email, and you can configure alert types, severity levels, and other parameters to customize the reporting criteria.

Statistics: Records all time‑synchronization logs and alarm logs, storing them separately; also tallies the number of clients, their IP addresses, and the request records for each IP.
Security: All management channels can be configured with strong encryption and enabled with certificate-based authentication, ensuring that communication content cannot be intercepted or stolen, and preventing malicious tampering with device configurations that could cause network-wide failures, thereby enhancing network security.
