V. Customer Requirements

University information systems have been developed in phases by multiple vendors, and each system employs different methods for obtaining time sources. During the project communication phase, the client’s key requirements were concentrated in the following areas:

• Unified time standard: Academic administration and course registration, campus card‑based payments and access control, security surveillance, research equipment, and other systems are distributed across separate networks. A unified, trusted time source is required to prevent inconsistencies in timestamps across these systems.
• Supports large-scale terminal access: Within the campus network, there are numerous user terminals and server devices in computer labs, as well as a wide array of IoT devices; therefore, the time server must provide reliable, high‑performance concurrent time synchronization.
• Business Continuity and Stability: Academic course registration, online examinations, and access control systems are time-sensitive; therefore, the time‑synchronization service must be highly redundant and provide uninterrupted operation.
• Local Time Source and Timekeeping Capability: It is necessary to use a locally deployed time server as the intranet’s time reference, ensuring continuous time output even when external time sources are unavailable.
• Auditable and Traceable: Logs, security events, and operational records must be timestamped uniformly and retained to facilitate post‑incident forensic analysis and compliance audits.
• Operability and Monitoring: It is necessary to centrally monitor the synchronization status and time offset of each client, with support for threshold-based alerts and report export, thereby reducing the daily operational workload.
