Jira issue originally created by user nicokaiser:
For the DateType type, "\Doctrine\DBAL\Platforms\MySqlPlatform::getDateTimeTypeDeclarationSql" returns "TIMESTAMP" in some cases, which leads to MySQL not allowing NULL values in DateTime fields. This breaks some models (where dates don't need to be set)... Why was that changed?
Comment created by @beberlei:
My mistake, in introduced this regression. I'll add a test and fix it.
