 cp is 64-bit clean (its timestamp handling is very simple) so this
 really must be happening in the kernel somewhere.
 
 Given that it appears to be machine-dependent, it's probably in the
 timecounters somewhere, as it's pretty hard to get machine-dependent
 behavior in filesystem code. Unless it's an endianness bug; but if so
 I'd expect it not to appear on alpha.
