IFC mapping for clock

Anyone has a suggestion on the IFC entity that a clock (pic below) should be mapped to?
(At least the closest one)
(Other than IfcBuiltElement )

This is probably where the (lack of) functional IFC conceptual model ends. How about linking to some concept defined in bSDD?

Either IfcFurniture or IfcAudioVisualAppliance in the case of digital clocks and displays.

IfcElectricTimeControl.PREDEFINEDTYPE.TIMECLOCK within IFC4 ADD2, and either IfcAudioVisualAppliance or IfcFlowController within IFC2x3 Schema.

Thanks Burcu. Although, I’m afraid that the semantics of IfcElectricTimeControl does not apply to clocks

An electric time control is a device that applies control to the provision or flow of electrical energy over time

Seems that IfcAudioVisualAppliance is the preferred candidate
