LocalDateTime

A local date-time string (i.e., with no associated timezone) in YYYY-MM-DDTHH:mm:ss format, e.g. 2020-01-01T00:00:00. The value is serialized and deserialized as a string as a signal to both clients and resolvers that special care must be taken with the value when converting it to any date/time type that includes a timezone, e.g., a JavaScript Date.
