Description
Updates the description of
hourCycleoption to reflect the current spec, which uses locale-dependent data to determine what hour cycles should be used for each locale whenhourCycleis set.Motivation
tc39/ecma402#758 changed how this option is interpreted; previous versions used very buggy algorithm to determine which hour cycle to use.
Note that no locale uses the
"h24"hour cycle, and only one region (JP) uses"h11".
