Yeah i went for Copyright because of the complexities.
at.c which we could call main() is GPLv2+
parsetime.pl should be ingnored (tests, not installed, not used).
Only posixtm.c is v3+ but since it's linked to the other bits that are
v2+ the whole thing should probably be called v3+ (you can go down is my
interpretation, but you can go up).
