This implements the normative change in tc39/proposal-temporal#2287 which reached consensus at the July 2022 TC39 meeting. It adds tests that ensure that PlainTime strings which require a T designator for disambiguation, are not disambiguated by adding a calendar annotation.

This gained consensus at the July 2022 TC39 plenary. Tests are now available in tc39/test262#3641. I had some last minute doubts about whether this one was actually correct, but I'm convinced by the discussion in #2285. |
