This is, I'll admit, a nit, but I'd suggest otherwise.  I pay a
lot of attention to file modification times, and I often transfer
files between different operating systems (Unix, VMS, MS-DOS)
while attempting to preserve modification times (using tar and
the like).  This means that I have a problem if I take a file
last modified in 1979 to an MS-DOS system, because DOS's epoch is
1980.  (The problem is theoretically even worse when moving files
from VMS, which has an epoch of 1865 or so.)  Not much of a
problem in practice, but it's something to think about.  (And, of
course, it's insoluble.)
