The system employs **Byzantine fault-tolerant consensus algorithms** to aggregate time data from multiple Network Time Protocol (NTP) sources, achieving **sub-second accuracy** while maintaining resilience against up to *f* faulty or malicious sources in a *2f+1* configuration. A **blockchain-inspired audit trail** provides cryptographic verification of all time adjustments, enabling forensic analysis and tamper detection. The implementation leverages platform-specific system calls across Linux, Windows, and macOS, with security hardening through **capability-based access control** and **HMAC-signed audit chains**. Experimental results demonstrate **98.7% consensus achievement rate** with median deviation of **0.8 seconds** across heterogeneous NTP sources, while maintaining audit log integrity under simulated attack scenarios.
