> Currently, when we perform count with timestamp types, it prints the internal
> representation as the column name as below:
> {code}
> scala> Seq(new
> java.sql.Timestamp(1)).toDF("a").groupBy("a").pivot("a").count().show()
> +--------------------+----+
> | a|1000|
> +--------------------+----+
> |1969-12-31 16:00:...| 1|
> +--------------------+----+
> {code}
> It seems this should be
> {code}
> +--------------------+-----------------------+
> | a|1969-12-31 16:00:00.001|
> +--------------------+-----------------------+
