Variable DateTime Type using date_create() instead of DateTime::createFromFormat().
This type has performance implications as it runs twice as long as the
Doctrine\DBAL\Types\DateTimeType, however in certain PostgreSQL configurations with
TIMESTAMP(n) columns where n > 0 it is necessary to use this type.
