This gets us one small step closer to lifting the VFS limit by using
struct inode_time in ext3. The on-disk format limit is lifted in ext4,
which will work until 2514.

This may be what the spec says, but when I experimented with this just
now it does seem that both ext2 and ext3 actually interpret timestamps
as *signed* 32-bit seconds.
