This is blocking everything proposed to Oslo right now.

Looks like this is an upstream bug: https://bitbucket.org/micktwomey/pyiso8601/issue/8/015-parses-negative-timezones-incorrectly

Fix proposed to branch: master

I believe there is one more bug that needs to be fixed upstream - https://bitbucket.org/micktwomey/pyiso8601/issue/9/regression-parsing-microseconds

    Skip bad versions of iso8601

    0.1.7 is now released (https://pypi.python.org/pypi/iso8601). We
    do need to allow folks to use the old 0.1.4 or the new 0.1.7 and
    avoid the two bad versions (0.1.5 and 0.1.6)
