Hive and Impala query result not matching [timestamp] - hadoop

Question

I'm working on a code where we are removing impala connection to hive beeline. changes are working as we expected. but when we try to query some data using impala , it came up with some additional timestamp with the date.
Sample Query: select cob_date from xxx_table where cob_date='2022-03-20';
outcome of the above query in impala is : 2022-03-20 05:00:00
but usually it will return like : 2022-03-20 00:00:00
but the same query giving proper response when try from hive : 2022-03-20 00:00:00
can anyone help me to understand whats going on here.
Thanks in advance .
