./driver/char/rtc.c:rtc_init()
#if defined(__alpha__) || defined(__mips__)
[...]

MIPS does that as well _in the wrong way_ compared to rtc.c:
./arch/mips/dev/time.c:time_init()
    /*
     * The DECstation RTC is used as a TOY (Time Of Year).
     * The PROM will reset the year to either '70, '71 or '72.
     * This hack will only work until Dec 31 2001.
     */
    year += 1928;
