isValidTime

Signature

isValidTime(value: string): boolean

Return true when value is a valid ISO PlainTime string.

• The part before the first annotation must match plainTime.
• Reads RFC 9557 annotations as Temporal.PlainTime.from does: elective ones ([foo=bar]), a time zone annotation and a calendar annotation are ignored (a time has no calendar), and an unknown critical one ([!foo=bar]) is rejected.
• Rejects leap seconds (e.g., “23:59:60”).
• Rejects invalid times (e.g., “24:00:00”, “23:60:00”).
