1. Proposed title of this feature request

[Samsung] Support for Event Notification in NTP-Only Environments (Chrony)

2. What is the nature and description of the request?

Samsung requests the ability to generate and handle event notifications (e.g., LOCKED, FREERUN) in an environment where only NTP (Chrony) is present — without any GNSS (GPS) source.

Currently, event notifications such as LOCKED, HOLDOVER, or FREERUN are typically associated with GNSS+NTP hybrid configurations.
However, in certain deployment environments (e.g., GSM/BSC systems), Samsung plans to operate time synchronization using only NTP servers managed by Chrony, without GNSS hardware.

The requested enhancement is to enable Chrony (NTP-only) systems to:

• Detect and generate LOCKED and FREERUN state events based solely on NTP source availability and stability.

• Propagate these events through the existing event notification framework (e.g., cloud-event-proxy or similar interface) for monitoring and alarm systems.

3. Why does the customer need this? (List the business requirements here)

• Alarm Integration: Samsung’s GSM/BSC environment requires event-driven alarms for synchronization health.

• Use Case Alignment: The feature supports Samsung’s internal time-synchronization framework, where NTP is used independently, and synchronization state needs to be monitored and alarmed.

4. List any affected packages or components.

• chrony

• cloud-event-proxy (for event notification propagation)
