Is there a way to know exactly since when a node/interface/volume is in its current status?

For Nodes I've tried getting the last event, but this does not seem to be reliable, and even matching the last event related to the status (i.e. status down > last down event) seems unreliable.

I see that for interfaces there is a value inside the interfaces view "InterfaceLastChange" but I can't be sure that this is a valid parameter either.

Thank you.
