Time sync: Internal callbacks for time #31398

Open cecille opened 8 months ago

cecille commented 8 months ago

Feature description

... There are now some clusters that would like to use the time sync cluster as a way to determine if the device has wall clock time. It would be nice to allow internal code to receive callbacks for certain attribute changes and events.

This is something that may well apply external to the time cluster as well - like an internal attribute subscription.

https://github.com/project-chip/connectedhomeip/pull/30562 did add a initial mechanism for this. Maybe that can be used as a starting point.
