> Currently, the basic type {{Date}} is not implemented in the Table API. In order to have a mapping of the most important ANSI SQL types for FLINK-2099. It makes sense to add support for {{Date}} to represent date, time and timestamps of milliseconds precision.
> Only the types `LONG` and `STRING` can be casted to `DATE` and vice versa. A `LONG` casted to `DATE` must be a milliseconds timestamp. A `STRING` casted to `DATE` must have the format "`yyyy-MM-dd HH:mm:ss.SSS`", "`yyyy-MM-dd`", "`HH:mm:ss`", or a milliseconds timestamp. All timestamps refer to the UTC timezone beginning from January 1, 1970, 00:00:00 in milliseconds.
