The new code is much less invasive. I'm currently debugging, why do_settimeofday64() accesses address 0x0. Maybe I'm calling it too early but I think, that I will figure this out.
Hm, that's unfortunate... Did you have a look into read_persistent_clock64() (timekeeping.c in Linux)? Maybe this is even less invasive than calling do_settimeofday64() as you may just implement the function that is defined "weak" in timekeeping.c. The related call chain is
timekeeping_init() -> read_persistent_wall_and_boot_offset() -- weak -> read_persistent_clock64 -- weak
