time_t is signed long.  Besides, git uses textual representation, its
just a matter of putting minus sign.  We can always fall back to
low level git-hash-object.

I'm just not sure if 'git commit' can work with dates prior to Unix
epoch.  I guess that git has some sanity checks that flies in the face
of such ab)use of git.
