-**[REQ-TECH-5]** All system components shall be synchronised to the same time that is acceptable for the system accuracy.
For high risk:
-**[REQ-TECH-6]** All system time drifts shall be monitored.
-**[REQ-TECH-6]** All system time drift corrections shall be recorded as monitoring event.
-**[REQ-TECH-7]** The product shall be designed in a way, that all cryptographic keys can be replaced with user controlled keys.
> Note: REQ-TECH-7 wording is not limited to 'user accessible and controllable' cryptographic keying, but implements the ability for the system user to achieve sovereignty.
