Subject [jira] [Commented] (HIVE-14412) Add a timezone-aware timestamp
Date Tue, 09 May 2017 16:09:04 GMT


Ashutosh Chauhan commented on HIVE-14412:

Is there any reason to use timestamptz alias for type timestamp with time zone? timestamptz
is non-standard. My suggestion is to not use reserve the word in grammar if not its not needed.

> 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.
