What changes, BIOS time or operating system time? :-?

If it's BIOS time, at least it seems a symptom of "low battery".

What I do is to write down the BIOS values of *any* section (or take a 
snapshot with dsc camera). Then change the battery, and before the system 
starts, enter into the BIOS and manually restore/check the values.

Important ones are hard disk "sata modes" (sata, ahci, raid) if present.

Dunno for old motherboards :-?

It's quite possible that today's newer models come with some integrated 
"led" into the board to warn the user about this. 

I've heard that some Gigabyte motherboards use embedded "dual-bios", so 
in the event one gets corrupted, you still have the "secondary". That's a 
nice feature :-)
