        - Fix CPAN RT bug 44167/54990: Negative milliseconds/microseconds.
          This was a boneheaded mistake I should have fixed years ago.
          Many thanks to Karl Moens for reporting the error, and for a patch.

        - Fix CPAN RT bug 47229: Build.PL dependencies.
          Unfortunately, I cannot fix Makefile.PL, since ExtUtils::MakeMaker
          has no concept of "recommended" or "optional" modules.
          Thanks to Jens Rehsack for the suggestion.

        - Fix CPAN RT bug 55630: ISO-8601 Z (Zulu, UTC) marker not supported.
          Thanks to Will Coleda for pointing this out.

        - Fix CPAN RT bug 76705/76707 (maybe): month out of range.
          I can't reproduce this bug, but I made a change to the time parsing
          that might fix it.  Thanks to Todd Bezenek for reporting the problem.
