Tampering with hubby's computer

[Derek Trotter]

The woman in this story is charged with putting some fairly disgusting 
stuff on her husband's computer in an attempt to frame him.  
Investigators checked out the computer and found the pictures were put 
on the computer at a time when her husband wasn't at home.

With linux is there a log that  is usually kept or that could be enabled 
that would log any changes in the system's date or time? Is there a way 
to tell if someone had gone into the bios, changed the date and then 
changed it back?  I have to wonder if this woman would have gotten away 
with it if she had changed the date before putting the pictures on the 
computer, then changing it back.
