class TimestampNormalizer

Converts values for the Timestamp data type to and from common formats.

@internal

Note that \Drupal\Core\TypedData\Plugin\DataType\Timestamp::getDateTime() explicitly sets a default timezone of UTC. This ensures the string representation generated by DateTimeNormalizer::normalize() is also in UTC.
