Date Only
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.
