    1. Update TZInfo version in lib/active_support/vendor.rb
    2. gem uninstall tzinfo on local system before running tests, to ensure tests are running against bundled version
    
    If a test fails because a particular zone can't be found, it's likely because the TZInfo identifier in the
    ActiveSupport::TimeZone::MAPPING hash is referencing a linked timezone instead of referencing the timezone directly.
    In this case, just change the MAPPING value to the correct identifier, and unpack TZInfo again.
