xueyumusic commented on issue #6282: [FLINK-6847][FLINK-6813] [table] TimestampDiff table
api and sql support
URL: https://github.com/apache/flink/pull/6282#issuecomment-410518086
   @twalthr @hequn8128 I updated with the following
   1. using `-` arithmetic to compute diff of two timestamps or dates, the result is milliseconds.
The behavior is like `unix_timestamp('2018-07-05 10:00:00') - unix_timestamp('2018-07-03 09:00:00')`
   2. For timestampDiff function, it looks that I have no good way to express the result interval
unit using `-` right now, so just leave it orignal currently and only fixed some above feedbacks
of @hequn8128
