/**
 * Converts date/datetime from one format to another.
 *
 * Available configuration keys
 * - from_format: The source format string as accepted by
 *   @link http://php.net/manual/datetime.createfromformat.php \DateTime::createFromFormat. @endlink
 * - to_format: The destination format.
 * - timezone: (deprecated) String identifying the required time zone, see
 *   DateTimePlus::__construct(). The timezone configuration key is deprecated
 *   in Drupal 8.4.x and will be removed before Drupal 9.0.0, use from_timezone
 *   and to_timezone instead.
 * - from_timezone: String identifying the required source time zone, see
 *   DateTimePlus::__construct().
 * - to_timezone: String identifying the required destination time zone, see
 *   DateTimePlus::__construct().
 * - settings: keyed array of settings, see DateTimePlus::__construct().
 *
 * Configuration keys from_timezone and to_timezone are both optional. Possible
 * input variants:
 * - Both from_timezone and to_timezone are empty. Date will not be converted
 *   and be treated as date in default timezone.
 * - Only from_timezone is set. Date will be converted from timezone specified
 *   in from_timezone key to the default timezone.
 * - Only to_timezone is set. Date will be converted from the default timezone
 *   to the timezone specified in to_timezone key.
 * - Both from_timezone and to_timezone are set. Date will be converted from
 *   timezone specified in from_timezone key to the timezone specified in
 *   to_timezone key.
 *
 * Examples:
 *
 * Example usage for date only fields
 * (DateTimeItemInterface::DATE_STORAGE_FORMAT):
 * @code
 * process:
 *   field_date:
 *     plugin: format_date
 *     from_format: 'm/d/Y'
 *     to_format: 'Y-m-d'
 *     source: event_date
 * @endcode
 *
 * If the source value was '01/05/1955' the transformed value would be
 * 1955-01-05.
 *
 * Example usage for datetime fields
 * (DateTimeItemInterface::DATETIME_STORAGE_FORMAT):
 * @code
 * process:
 *   field_time:
 *     plugin: format_date
 *     from_format: 'm/d/Y H:i:s'
 *     to_format: 'Y-m-d\TH:i:s'
 *     source: event_time
 * @endcode
 *
 * If the source value was '01/05/1955 10:43:22' the transformed value would be
 * 1955-01-05T10:43:22.
 *
 * Example usage for datetime fields with a timezone and settings:
 * @code
 * process:
 *   field_time:
 *     plugin: format_date
 *     from_format: 'Y-m-d\TH:i:sO'
 *     to_format: 'Y-m-d\TH:i:s'
 *     from_timezone: 'America/Managua'
 *     to_timezone: 'UTC'
 *     settings:
 *       validate_format: false
 *     source: event_time
 * @endcode
 *
 * If the source value was '2004-12-19T10:19:42-0600' the transformed value
 * would be 2004-12-19T10:19:42. Set validate_format to false if your source
 * value is '0000-00-00 00:00:00'.
