Review comment:
Right. But it doesn't seem very useful if the conversion is only a one-way
trip. For example, users are allowed to insert some low-precision timestamps
into a Hive table. But they cannot read these timestamps back because we don't
allow converting Hive timestamp to Flink timestamp, right?
