Subject [jira] [Commented] (HIVE-6009) Add from_unixtime UDF that has controllable Timezone
Date Thu, 05 Nov 2015 12:24:27 GMT

    [ https://issues.apache.org/jira/browse/HIVE-6009?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14991600#comment-14991600

Scott Eade commented on HIVE-6009:
----------------------------------

I think it would be more than "nice" to support this.  I think it is absolutely required.
 Given a unixtime ("number of seconds from unix epoch") there is currently now way that I
can see to use this value to get a UTC timestamp.  Sure I could use to_utc_timestamp(timestamp,
string timezone), but what value should I use for the timezone parameter?  Most other date
functions are running in UTC but this one suddenly takes the system timezone into account.
 Not very helpful.

> Currently the from_unixtime UDF takes into a account timezone of the system doing the
transformation. I think that implementation is good, but it would be nice to include or change
the current UDF to have a configurable timezone. 
> It would be useful for looking at timestamp data from different regions in the native
region's timezone. 
> Example: 
> from_unixtime(unix_time, format, timezone)
> from_unixtime(1293840000, dd MMM yyyy, GMT-5)
