Changelog
This standardizes provider-facing temporal contracts at the APIFuse boundary while preserving compact upstream formats internally. Regression coverage verifies representative input conversion to upstream compact parameters and output conversion back to ISO values for the migrated providers.
Update callers to send KMA baseDate and School Lunch mealDate as YYYY-MM-DD, KMA baseTime as HH:mm, KMA tmFc as an ISO 8601 datetime with timezone, and K-Startup announcement date filters as YYYY-MM-DD. Update response consumers to read Food Safety registered_date, KMA forecast date/time, K-Startup application dates, Law date fields, Naver Blog postdate, Naver Flight segment date, and School Lunch founded_date/meal_date as ISO YYYY-MM-DD or HH:mm rather than compact upstream strings.
