The implementation adds a containerized chronyd managed via a ptpconfig CRD, internal process controls to switch between phc2sys (GNSS/PTP) and chronyd (NTP) without full restarts, and a state machine driven by ts2phc log parsing to trigger failover or recovery. This keeps system clock accuracy within 1 millisecond even during prolonged GNSS outages. Future work includes O-RAN NTP event types and GNSS-to-PTP failover support. ## Full article daily.dev links to this article rather than hosting it.
