  -  Removed travis file from the tarball
        The tarball had a .travis.yml file in it that wasn't in the MANIFEST
        file. Since the MANIFEST file is automatically generated by the perl
        mkmanifest tool, since it didn't see the .travis.yml file, I have
        excluded it from the tarball. Reported by Mohammad S Anwar on GitHub
        (#23)

  -  Time zone fixes
        Newest zoneinfo data (tzdata 2018e)
