Alan Gates commented on HIVE-14412: ----------------------------------- Agree the TZ <-> non TZ conversions look like they match up with the spec. Using the GMT+/-HH:MM format for timezone matches the spec, but it does create a weird situation for many users where 1/2 the year their times will be off by an hour. I think the big question is can the underlying infrastructure handle it, as we don't want Hive in the business of understanding when DST starts and stops all over the world. > Add a timezone-aware timestamp > ------------------------------ > > Key: HIVE-14412 > URL: https://issues.apache.org/jira/browse/HIVE-14412 > Project: Hive > Issue Type: Sub-task > Components: Hive > Reporter: Rui Li > Assignee: Rui Li > Attachments: HIVE-14412.1.patch, HIVE-14412.2.patch, > HIVE-14412.3.patch, HIVE-14412.4.patch, HIVE-14412.5.patch, > HIVE-14412.6.patch, HIVE-14412.7.patch, HIVE-14412.8.patch > > > Java's Timestamp stores the time elapsed since the epoch. While it's by > itself unambiguous, ambiguity comes when we parse a string into timestamp, or > convert a timestamp to string, causing problems like HIVE-14305. > To solve the issue, I think we should make timestamp aware of timezone. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
