Perhaps the RTC was reset due to battery running out?  That would set
the year to 1900, but the kernel RTC interface cannot represent dates
before 1970.  Unfortunately hwclock insists on reading the RTC even when
you just want to write to it, so you cannot fix that with hwclock -w.
When the battery of my iBook has run out I'm using the following to
reset RTC to current time so that it is usable again.

Thanks! I did not know about this problem with the year. This vintage
of mac sets the year to 1956.

Yes, the battery is dead. It is one of those $20 1/3 AA lithium cells.
I can't afford to replace it. I went into the MacOS Classic date
control panel and set the year to 1971 and it worked!

Thanks for the tip. I would have never figured this one out!
