Event RTC_CHANGE is "emitted when the guest changes the RTC time" (and

w.r.t. RTC, a machine having multiple RTC devices is silly...
I don't think we have any examples in the tree currently, but
I bet real hardware like that does exist: the most plausible
thing would be a board where there's an RTC built into the SoC
but the board designers put an external RTC on the board (perhaps
because it was better/more accurate/easier to make battery-backed).
