If NTP is not reachable, what is a likely impact on the collaboration system?

Explanation:
Clock synchronization is crucial for certificate trust. When NTP isn’t reachable, devices’ clocks begin to drift. Certificate validation relies on the current time to check notBefore and notAfter windows. If the time is off, a certificate can appear expired or not yet valid, causing the TLS/DTLS handshake to fail and trust to be broken. That disruption prevents secure signaling and authentication, so certificates may fail to validate due to time drift. Other issues like DNS resolution or automatic video codec adjustments aren’t direct consequences of losing NTP access.
