Issue #2767779: Fix Field Caching for Status, but no hours

        // Make sure we only receive 1 day, only to calculate the cache.

        $office_hours = $this->getRows($settings, $field_settings, []);

        $next_day = array_shift($office_hours);

        if (!$next_day) {

          return Cache::PERMANENT;

        }

        // Get the difference in hours/minutes between 'now' and next open/closing time.

        $first_time = NULL;

        foreach ($next_day['slots'] as $slot) {

          $start = $slot['start'];

          $end = $slot['end'];
