Looks like your RTC has year=0 and rtc_init() concluded
epoch = 1952, while it should have left epoch as 1900.
Probably it would be much better if the kernel didnt try
to guess at all and left it to userspace (hwclock --setepoch)
to set the epoch. But if you want the kernel to guess, then
replacing
if (year > 10 && year < 44) {
epoch = 1980;
guess = "ARC console";
} else if (year < 96) {
epoch = 1952;
guess = "Digital UNIX";
}
by
if (year >= 20 && year < 48) {
epoch = 1980;
guess = "ARC console";
} else if (year >= 48 && year < 100) {
epoch = 1952;
guess = "Digital UNIX";
}
will work for a few years.
