-----------------------------------
Hi [~jeff-zou] ,
We cannot simple use `LocalDateTime.toString()` as in current implemetattion
Flink json format should support datetime with both ISO-8601 and SQL standard.
It seems that ISO-8601 does not explicitly stipulate the precision of
milliseconds or nanoseconds.
But personally I agree that the time format should be consistent.
See [JSON | Apache
