   *   A Twig_Environment instance.
   * @param int|string|DateTime $date
   *   A string, integer timestamp or DateTime object to convert.

   *   (optional) The format to use, one of:

   *     '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|null
   *   A translated date string in the requested format. Since the format may
   *   contain user input, this value should be escaped when output.
