[jira] [Commented] (DRILL-4226) TestExtendedTypes#checkReadWriteExtended fails when the time zone time zone is ahead of UTC

["Akihiko Kusanagi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DRILL-4226?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15072056#comment-15072056 ] 

Akihiko Kusanagi commented on DRILL-4226:
-----------------------------------------

The workaround is to add '-Duser.timezone=UTC' option to maven command:
{noformat}
mvn test -Duser.timezone=UTC 
{noformat}

> 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.
