What architecture?
What kernel version?
Are you in fact running xntpd?

Well, since you looked at the source:
For some randomly chosen kernel version and architecture it does
if (abs(real_minutes - cmos_minutes) < 30) {
update_cmos()
} else {
printk("set_rtc_mmss: can't update from %d to %d\n",
cmos_minutes, real_minutes);
}
so if your cmos time is 0.001 sec ahead of your system time
then around the hour you'll see
set_rtc_mmss: can't update from 0 to 59
Of course, messing with the cmos clock at all was a rather bad idea,
but that is a different discussion.
