02155da7bagot a claim about sacrificing ability to compare arbitrary `RUBY_DESCRIPTION`s without converting timezones. Because most of the people would be familiar with timezone conversion with UTC but it'd be harder when it comes to JST, this commit just changes the timezone inf42588f754to UTC. Another bonus in using UTC is that we can use a shorter variant of ISO 8601 format like "2019-06-10T14:26:24Z" (the last Z part).
