Subject [jira] [Commented] (HIVE-14412) Add a timezone-aware timestamp
Date Mon, 15 Aug 2016 17:54:20 GMT

Xuefu Zhang commented on HIVE-14412:
------------------------------------

[~lirui], your proposal looks good to me, especially it's backward compatible. I'm not sure
if this has any impact on vectorization, but it's great to make the encoding work well in
vectorized mode.

> 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.
