Overview

The TimeDaemon component is a system daemon responsible for quality assurance and providing synchronized time to local applications on the ECU. It reads raw synchronization data from shared memory (published by TimeSlave), performs quality checks and plausibility assessments, and provides the final score::time API to client applications.

For module-level integration and deployment information, see the main module manual.
