Stamatis Zampetakis commented on HIVE-25093:
--------------------------------------------
Hey [~ashish-kumar-sharma], I am a bit confused with your example. The result
that you get for the query seems to be the correct one; can you explain what is
wrong?
The formatting string that you specified asks explicitly (the 'z' in the end
means zero-offset or equivalently UTC) to format the timestamp in UTC timezone.
If UTC is not what you want the I guess you should specify another timezone.
> date_format() UDF is returning values in UTC time zone only

> Project: Hive
> Issue Type: Bug
> Components: UDF
> Affects Versions: 3.1.2
> Reporter: Ashish Sharma
> Assignee: Ashish Sharma
> Priority: Trivial
>
> Query - select date_format(current_timestamp,"yyyy-MM-dd HH:mm:ss.SSS z")
> Result - 2021-05-04 13:00:33.358 UTC
> As part of HIVE-12192 it was decided to have a common time zone for all
> computation i.e. "UTC". Due to which data_format() function was hard coded to
> "UTC".
> But later in HIVE-21039 it was decided that user session time zone value
> should be the default not UTC.
> date_format() was not fixed as part of HIVE-21039.
> what should be the ideal time zone value of date_format().
