Ravan updated DRILL-5250:
-------------------------
    Description: 
Query1: Connected to Oracle Database

select a1.empno,a1.HIREDATE as HIREDATE,a1.SAL as SAL from orcl.xx.EMP a1;

Output:-

EMPNO                   HIREDATE                        SAL
7369.0	1980-12-17T00:00:00.000+05:30	800.0
7499.0	1981-02-20T00:00:00.000+05:30	1600.0
7521.0	1981-02-22T00:00:00.000+05:30	1250.0
7566.0	1981-04-02T00:00:00.000+05:30	2975.0

Query2: Creating a hive table with above query and storage format is JSON

create table intermediate.HIVE.test_16 as  select a1.empno as EMPNO,a1.HIREDATE as HIREDATE,a1.SAL
as SAL from orcl.xx.EMP a1;

Query 3: 

SELECT * FROM intermediate.HIVE.test_16

Wrong Output for DATE column returning one day before date:

EMPNO                   HIREDATE                 SAL
