[jira] [Updated] (HIVE-14305) To/From UTC timestamp may return
incorrect result because of DST
[ https://issues.apache.org/jira/browse/HIVE-14305?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Rui Li updated HIVE-14305:
--------------------------
Description:
If the machine's local timezone involves DST, the UDFs return incorrect results.
For example:
{code}
select to_utc_timestamp('2005-04-03 02:01:00','UTC');
{code}
returns {{2005-04-03 03:01:00}}. Correct result should be {{2005-04-03 02:01:00}}.
{code}
select to_utc_timestamp('2005-04-03 10:01:00','Asia/Shanghai');
{code}
returns {{2005-04-03 03:01:00}}. Correct result should be {{2005-04-03 02:01:00}}.
