Jesus Camacho Rodriguez commented on HIVE-21039:
------------------------------------------------
[~ashutoshc], could you take a look? The q file changes are expected, since
session timestamp for those tests is taken from {{hive.test.currenttimestamp}}
property, which is set to '2012-01-01 01:02:03', and we are parsing it as local
now.
> CURRENT_TIMESTAMP returns value in UTC time zone

> Key: HIVE-21039
> URL: https://issues.apache.org/jira/browse/HIVE-21039
> Project: Hive
> Issue Type: Bug
> Affects Versions: 3.1.1
> Reporter: Andrey Zinovyev
> Assignee: Jesus Camacho Rodriguez
> Priority: Major
> Attachments: HIVE-21039.01.patch, HIVE-21039.02.patch

> We're upgrading from hive 1.2 to 3.1 and it seems like new hive returns
> CURRENT_TIMESTAMP in UTC timezone. But before it was in local (system's
> default) timezone.
> According to HIVE-5472 current_timestamp should use user's local timezone.
> This behaviour was changed in HIVE-12192 (if I got it right).
> GenericUDFCurrentTimestamp now explicitly uses UTC as timezone to initialise
> org.apache.hadoop.hive.common.type.Timestamp .
> For example
> Old hive:
> {code}
> hive> select current_timestamp;
> OK
> 2018-12-12 22:43:39.024
> {code}
> New hive:
> {code}
> > select current_timestamp;
