Sigh. These notifiers have been proposed in the past and we always
rejected them. Why do you need this? There should be nothing except
the core timekeeping code which needs to know about clock_was_set.

Can you please explain what kind of users you have in mind and WHY
they need to know about it.

Thanks,
