Right, after discussion with Gregory, I found out my misunderstanding.
I'm looking now as to how this clock affects the system behavior. I
indeed see this clock ->disable() hook being called, but it doesn't
seem to cause any sort of problem on the system. It still works nicely.
So not sure this clock is actually doing something, or at least maybe
not what we think it does.

Best regards,

Thomas
