gem 'tzinfo', '< 2.0.0' no errors

It turns out that raise 4 specifies a version of tzinfo. I'm guessing that rails 3 does not. So this isn't a problem for much of anyone - unless they are still using rails 3 and somehow also tzinfo >=2 - which seems unlikely.

Maybe change the Gemfile so that it specifies tzinfo < 2?

And maybe also update it to activesupport 4-6...
