Test queries are like this:
{noformat}
ALTER SESSION SET `store.format` = 'json' 
ALTER SESSION SET `store.json.extended_types` = true
create table dfs_test.tmp.`TestExtendedTypes/newjson` as select * from dfs.`${WORKING_PATH}/src/test/resources/vector/complex/extended.json`
{noformat}
It seems that Drill parses '1997-07-16' as a UTC date but writes it as a local date. If the system time zone is ahead of UTC, it will be changed to '1997-07-15'. I understand this is the current limitation, but the test code or configuration should be aware of it.
