Is there something wrong with 'show'?

Heh, you fooled me, and Peff is right.  "test-date show" does not
interpret its input any way other than as seconds-since-epoch.

I agree with the "native->internal" part of the suggestion.  What see by
default in "git show" output is merely the ctime(3) format followed by
timezone.  I don't mind if we call that "git native", even though I
suspect we do _not have to_ invent new word for that.

Also "test-date parse" seems to accept things like these:

    '2009.04.07 20:21:22 -0000'
    '04/07/2009 20:21:22 -0000'
    '07.04.2009 20:21:22 -0000'
