Hi,

As I can see efi_set_rtc_mmss() is never used to set RTC.
Even on EFI platform mach_set_rtc_mmss() is called and does
that thing. Why it is done in that way? It is a bug or it was
done intentionally. Am I missing something?

Daniel

EFI services generally don't work properly. The less they are used the
better. We can realistically only make an EFI call with the same
parameters windows does under the same kind of circumstances because the
firmware on many motherboards is complete sh*te.
