It does - which means that Bruce's interpretation is wrong, because I do  
have files with dates of 1969 on my disk (and so has everybody who  
installed doc-rfc).

Of course, in reality, it's irrelevant what ext2 uses (so long as it's 32  
bits), because ext2 doesn't interpret those dates. Linux, OTOH, does.  
Which means reformat in 2038.
