Following reasons caused mismatches: - different handling of invalid values; - different CAST results with fractional seconds; - microseconds support in MariaDB; - different algorithm of comparing temporal values; - differences in error and warning texts and codes; - different approach to truncating datetime values to time; - additional collations; - different record order for queries without ORDER BY; - MySQL bug#66034. More details in MDEV-369 comments.
