Introduction

Government‑level information technology innovation (ITI) is one of the core application scenarios for domestic substitution, with its primary requirement being end‑to‑end autonomy, controllability, and compliance across hardware, software, and data. As a foundational enabler for government data exchange and business collaboration, time‑synchronization systems directly impact the stability and data security of government information systems. Drawing on the compliance requirements of government ITI projects, this paper provides a detailed overview of the construction standards, adaptation considerations, and practical implementation of time‑synchronization systems, offering valuable guidance for users in the public sector.

I. Compliance Requirements for Time Synchronization Systems in Government IT Innovation Projects

1. Domestication and compliance support : Hardware (chips, servers) and software (operating systems, databases) listed in the IT innovation catalog must be integrated; for example, Hygon can be adopted. / A time server based on Phytium chips, compatible with Kylin, UOS Wait for domestically developed operating systems to avoid project acceptance being stalled by products not listed on the XinChuang catalog.
2. Security Level Compliance : Meets the requirements of “Information Security Technology” In accordance with the Level 3 and above requirements of the “Basic Requirements for Cybersecurity Classified Protection,” the system shall incorporate security features such as identity authentication, access control, log auditing, and data encryption to prevent unauthorized access and data tampering.
3. Time accuracy compliance : Scenarios such as government data exchange and e-government approvals require high-precision time synchronization. ≤1ms ; For critical applications such as financial regulation and emergency command, precision must be enhanced to the nanosecond level to ensure timestamp consistency across business processes.

II. Key Considerations for Building a Government‑Led Information Technology Innovation Time Synchronization System

1. Architecture Selection : Recommended to adopt “ Centralized Timing + Distributed Synchronization ” Architecture, composed of 1 The core Beidou timing server on the Taiwan side serves as the time reference, distributing time signals via the local area network to various government terminals and business systems, and is integrated with a centralized management platform to enable end-to-end monitoring. For example, in a certain municipal-level government cloud project, Zhongxin Chuang was adopted. DNTS-9HG Time server, for 300 + The government application system provides a unified time synchronization service, meeting the requirements for cross-departmental data exchange.
2. Compatibility testing : Completed compatibility testing with the indigenous innovation (XinChuang) ecosystem ahead of schedule, covering domestic servers (Huawei TaiShan, Inspur CloudSea), databases (RenDa JinCang, Dameng), and middleware (TongWeb, Kingdee TianYan), ensuring seamless system integration and zero compatibility issues.
3. Redundant backup : Critical government‑related scenarios require a dual‑server hot‑standby configuration, with the two time servers serving as mutual backups. When the primary device fails, the standby server automatically takes over, with a switchover time of… ≤3 Seconds, ensuring uninterrupted time synchronization services; meanwhile, device configurations and operation logs are regularly backed up to facilitate fault tracing and recovery.

III. Common Issues and Solutions in Implementation

1. Inconsistent time offsets across multiple systems : Due to the government information system involving equipment from various vendors, some legacy systems have incompatible synchronization protocols, resulting in time discrepancies. Solution: Adopt a solution that supports NTP 、 PTP 、 SNTP A multi-protocol time server achieves system-wide synchronization through protocol adaptation; meanwhile, the management platform is configured to issue alerts when time offsets exceed a set threshold, triggering automatic calibration upon threshold breach.
2. Unstable satellite signal reception : Government data centers are often located underground or in densely built-up urban areas, where satellite signals can easily be obstructed. Solution: Deploy an external high-gain BeiDou antenna on an open rooftop of the data center and connect it to the time server via an extension cable. The antenna should be positioned away from obstructions and sources of electromagnetic interference, such as radar systems and microwave equipment.
3. Compliance documentation is missing. : During project acceptance, documentation such as the localization adaptation certificate, classified protection test report, and IT innovation product catalog certification must be provided. Solution: Select a time server vendor that has already been included in the IT innovation product catalog, and coordinate with the vendor in advance to obtain the relevant certification documents, ensuring a smooth acceptance process.

Conclusion

In government‑related information technology innovation (ITI) projects, compliant implementation of a time‑synchronization system is both foundational and critical. Enterprises must, in alignment with project requirements, select time‑synchronization solutions that meet ITI standards, ensure security and controllability, and offer robust compatibility, while also prioritizing architectural design, redundancy and backup measures, and the preparation of compliance documentation. As a vendor recommended on the ITI product list, Zhongxin Chuang has provided time‑synchronization services for numerous provincial‑level government ITI initiatives, amassing extensive practical experience and offering end‑to‑end compliance‑driven support to public‑sector clients.
