All the failures seem quite random to me but the reports I get are not

I know it happens with PCF8523 and that can be true because the
datasheet says the date is undefined at reset. The handling of the OS
bit (that bit indicates the date is probably wrong) has to be fixed and
I will take care of that.

If that is the only RTC with that particular issue, we clearly don't
need my workaround. But As I say, I can ask but I don't have a clear
list of the affected system and their RTC.

I add that it also seem to affect the Allwinner A20 RTC. I'm not sure
how much we can trust the datasheet but it claims the reset value is 0
and I don't think there is a way to know whether the date is correct or
not.
