This adds an object, TemporalHelpers.ISO, which has methods that return
arrays of various ISO strings. The idea is to deduplicate more string
tests into methods on this object.
This implements the normative change in
https://github.com/tc39/proposal-temporal/pull/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 implements the normative change in
https://github.com/tc39/proposal-temporal/pull/2284 which reached
consensus at the July 2022 TC39 meeting.
It adds tests that ensure strings like HHMM-UU[TZ] and HHMMSS[TZ] do not
require a disambiguating T separator, even if HHMM-UU and HHMMSS would by
themselves.
Here's a test I should have included in #3395. It's allowed to replace the
"T" in the middle of an ISO string with a space, but not when the "T" is a
time designator prefix. This assertion ensures that implementations make
this distinction correctly.
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.
