However, what I am testing is a library that actually modifies
ActiveRecord behaviour based on the default_timezone setting. So, it is
pointless to mock or stub what I am actually testing. I eventually just
overrode the environment setting in the test itself.
it "should set the UTC time (for _at/_on) correctly" do
ActiveRecord::Base.default_timezone = "utc"
...
