Against the backdrop of the accelerated advancement of the information technology application innovation industry, critical information systems across various sectors are increasingly demanding independent and controllable core hardware and software. As time synchronization serves as a fundamental enabler for the coordinated operation of these systems, its domestic adaptation capability has become a key performance indicator for the successful implementation of IT application innovation projects. Beijing Zhongxinchuang Technology Co., Ltd. has been deeply engaged in the field of time synchronization. For more than 20 years, leveraging mainstream domestic CPU platforms such as Hygon and Phytium, we have independently developed and launched the DNTS‑9HG domestically produced, indigenous‑innovation time‑synchronization server. It is fully compatible with domestic operating systems including Kylin and UOS, providing a secure and controllable time‑reference solution to support indigenous‑innovation upgrades across industries such as finance, government affairs, transportation, and energy.

The DNTS-9HG’s localization strategy spans the entire hardware and software value chain. On the hardware side, its core processor leverages domestically produced chips from the Hygon 3000/5000 series or the Phytium 2000+/5000 series, while key components such as memory, storage drives, power supplies, and motherboards are sourced from leading domestic suppliers. Rigorous compatibility testing and stability validation ensure that the hardware system is free from external technological dependencies, thereby mitigating supply-chain security risks at their root. The device features a standard rack‑mount design with dimensions compatible with conventional data‑center cabinets, supports redundant power configurations, and meets the demanding requirements of industrial‑grade, 7×24 uninterrupted operation, achieving an industry‑leading mean time between failures (MTBF).

At the software level, the device is equipped with an intelligent, network-wide time‑synchronization monitoring software independently developed by Zhongxin Chuang. Version 4.0: This software has obtained a Computer Software Copyright Registration Certificate and is designed with a B/S architecture, eliminating the need to install additional client‑side applications. Operations and maintenance personnel can access the management interface via any web browser, enabling centralized control of time‑synchronization devices across the entire network. Its functional modules cover core use cases such as device management, status monitoring, time calibration, alarm configuration, asset management, and log auditing. The system supports real-time display of key parameters for each endpoint, including time offset, satellite signal strength, and network connection status, with a highly flexible data‑sampling interval that can be configured down to the millisecond level. For abnormal scenarios, the software offers multiple alerting methods—email, SMS, audible and visual alarms, and pop‑up notifications—and allows users to customize alarm thresholds, ensuring prompt response to issues such as time drift, device disconnection, or signal loss.

In terms of timing performance, The DNTS-9HG supports time synchronization via the BeiDou single‑system or a BeiDou/GPS dual‑mode configuration, allowing flexible switching between time sources to meet the independent and controllable requirements of information‑technology innovation projects. With timing accuracy at the nanosecond level, it satisfies the stringent time‑precision demands of applications such as financial trading, government data exchange, and industrial control. The device features a built-in high‑precision temperature‑compensated crystal oscillator; in extreme conditions where satellite signals are blocked or interrupted, its holdover module ensures long‑term timekeeping accuracy, with holdover error maintained at the microsecond‑per‑day level, thereby safeguarding business systems from the impact of time‑source anomalies. Furthermore, the device supports multiple time‑synchronization protocols, including NTPv1/v2/v3/v4 and SNTP, and is compatible with network transport protocols such as TCP/IP and UDP. It can seamlessly integrate with domestically developed databases, middleware, and business systems, adapting to complex information‑technology‑innovation network environments.

Currently, The DNTS‑9HG domestically produced, information‑technology‑innovation‑compliant time‑synchronization server has successfully passed the relevant adaptation certification issued by the Information Technology Application Innovation Working Committee and has been deployed in numerous IT‑innovation projects, including provincial government clouds, data centers of state‑owned banks, and production systems of energy enterprises. In a provincial government service platform upgrade project, this device provided a unified time reference for the government service systems across 13 prefecture‑level cities in the province, ensuring temporal consistency in cross‑departmental data exchange, electronic certificate and license approvals, and the processing of administrative matters, thereby enhancing both the efficiency of government services and public satisfaction. In another state‑owned bank’s IT‑innovation transformation project, the DNTS‑9HG delivered independently controllable time‑synchronization services to core transaction, clearing, and risk‑control systems, meeting the China Banking and Insurance Regulatory Commission’s regulatory requirements for the security of financial information systems.
