Timestamp Offset
The return type is expected to be an OffsetDateTime value. Arcade converts the return type to an OffsetDateTime via the following transformations:
OffsetDateTime objects are returned unchanged.
Instant objects display their offset from UTC based on their timezone.
LocalDate objects are converted assuming the time is midnight with no offset from UTC.
strings are parsed if they match the ISO 8601 format, YYYY-MM-DDTHH:MM:SS+/-HH::MM.
all other types are converted to null.
