description: >
|
|
Tests that fallbacks for deprecated calendars are selected from one of the
|
|
values returned from `AvailableCalendars`.
|
|
info: |
|
|
CreateDateTimeFormat ( _newTarget_, _locales_, _options_, _required_, _defaults_ )
|
|
|
|
...
|
|
9. If _resolvedCalendar_ is *"islamic"* or *"islamic-rgsa"*, then
|
|
a. Let _fallbackCalendar_ be an implementation- and locale-defined calendar type that is one of the values returned from AvailableCalendars.
|
|
b. Set _resolvedCalendar_ to CanonicalizeUValue(*"ca"*, _fallbackCalendar_).
|
|
c. If the ECMAScript implementation has a mechanism for reporting diagnostic warning messages, a warning should be issued.
|
|
10. Set _dateTimeFormat_.[[Calendar]] to _resolvedCalendar_.
