DateOnly

The return type is expected to be a LocalDate value. Arcade converts the return type to a LocalDate via the following transformations:

• LocalDate objects are returned unchanged.

• Instant objects are converted by removing their time component.

• OffsetDateTime objects are converted by removing their time component and offset.

• strings are parsed if they match the ISO 8601 format, YYYY-MM-DD.

• all other types are converted to null.
