So who will be in charge of updating the RTC now? The update
every 11 min is there to stay on x86(-64) it seems.
Removing this will have strange side effects: as an example,
your laptop clock will be good if it synchronized on NTP,
then you put it to sleep, disconnect the network and RTC read
on wake up returns a wrong value, giving wrong timestamps.
As someone who has a network of tens of machines using
NTP for synchornisation I think it is a very bad idea
unless we have a replacement.
