Namespace

Code

protected $allowedFormats = [
  'RFC 3339' => \DateTime::RFC3339,
  'ISO 8601' => \DateTime::ISO8601,
  // @todo Remove this in https://www.drupal.org/project/drupal/issues/2958416.
  // RFC3339 only covers combined date and time representations. For date-only
  // representations, we need to use ISO 8601. There isn't a constant on the
  // \DateTime class that we can use, so we have to hardcode the format.
  // @see https://en.wikipedia.org/wiki/ISO_8601#Calendar_dates
  // @see \Drupal\datetime\Plugin\Field\FieldType\DateTimeItemInterface::DATE_STORAGE_FORMAT
