Backup Batt or something ELSE? G4 Powerbook 867

Have been experiencing slow reboots..
In effort to find out why, did a 'command - s' boot for a file check...
Noted that the data on the screen included dates of 1969 and so forth, not the current date.
In a Win machine, the Bios battery would be faulty.

Why would this PB G4 show such a wrong date? I have found and I have deleted files on the machine with modification dates of 1969.

Many thanks.

Still looking for help on this...
