Alexander Pivovarov commented on HIVE-6009:
-------------------------------------------
you can convert bigint to UTC timestamp and then convert UTC timestamp to GMT-5
timestamp (EST)
{code}
select from_unixtime(1293840000);
2010-12-31 16:00:00 // in Greenwich
select from_utc_timestamp(from_unixtime(1293840000), 'GMT-5');
2010-12-31 11:00:00 // in NYC
> Add from_unixtime UDF that has controllable Timezone

> Key: HIVE-6009
> URL: https://issues.apache.org/jira/browse/HIVE-6009
> Project: Hive
> Issue Type: Improvement
> Components: CLI
> Affects Versions: 0.10.0
> Environment: CDH4.4
> Reporter: Johndee Burks
> Priority: Trivial
>
> 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)
