I have a different problem. My clock always (or used to always,
I don't look anymore) go to the year 1933/2033. Some software
thought it was 1933, some 2033. I suspect one or the other date
was generated using two fixed digits (ie at 19 or 20) and the
other is the "correct" interpretation.

But no matter, now I maintain the time by saving it in a file
every two minutes and restoring it on reboot (using ntp to
correct, but I'm worried mostly about monotonicity). Not hard;
but if anyone wants the scripts..

I still don't know if this was Linux, my IBM 483DX-33 hardware,
or the clock battery, but "it's fixed in software now, so who
cares if the hardware works." ... It may have booted the correct
time the last 30 boots; I haven't checked the BIOS time recently.

But, it no longer gives checksum errors every boot, so it may
have "healed". If you ignore a problem long enough ...
