  /**
   * Formats a date, using a date type or a custom date format string.
   *
   * @param int $timestamp
   *   A UNIX timestamp to format.
   * @param string $type
   *   (optional) The format to use, one of:
   *   - One of the built-in formats: 'short', 'medium',
   *     'long', 'html_datetime', 'html_date', 'html_time',
   *     'html_yearless_date', 'html_week', 'html_month', 'html_year'.
   *   - The name of a date type defined by a date format config entity.
   *   - The machine name of an administrator-defined date format.
   *   - 'custom', to use $format.
   *   Defaults to 'medium'.
   * @param string $format
   *   (optional) If $type is 'custom', a PHP date format string suitable for
   *   input to date(). Use a backslash to escape ordinary text, so it does not
   *   get interpreted as date format characters.
   * @param string|null $timezone
   *   (optional) Time zone identifier, as described at
   *   http://php.net/manual/timezones.php Defaults to the time zone used to
   *   display the page.
   * @param string|null $langcode
   *   (optional) Language code to translate to. NULL (default) means to use
   *   the user interface language for the page.
   *
   * @return string
   *   A translated date string in the requested format. Since the format may
   *   contain user input, this value should be escaped when output.

   * possible to make a more exact representation, given that there is only one
   * input in seconds. If you are formatting an interval between two specific
   * timestamps, use \Drupal\Core\Datetime\DateFormatter::formatDiff() instead.
   *
   * @param int $interval
   *   The length of the interval in seconds.
   * @param int $granularity
   *   (optional) How many different units to display in the string (2 by
   *   default).
   * @param string|null $langcode
   *   (optional) langcode: The language code for the language used to format
   *   the date. Defaults to NULL, which results in the user interface language
   *   for the page being used.
