https://github.com/tc39/proposal-temporal/pull/1952 added support for time designator prefixes in PlainTime strings. This adds three tests to all entry points that convert an ISO string to a PlainTime: - no-implicit-midnight: ISO strings with only a date and no time are no longer accepted. Previously they were implicitly interpreted as 00:00. - with-time-designator: Tests that various forms of string with time designator are correctly parsed. - time-designator-required-for-disambiguation: Tests various cases where a string without a time designator is ambiguous and therefore the time designator is required, as well as various cases that implementations might assume are ambiguous but in fact are not. This was a normative change that achieved consensus at the December 2021 TC39 meeting.
