Subject [jira] [Created] (HIVE-6009) Add from_unixtime UDF that has controllable Timezone
Date Wed, 11 Dec 2013 21:09:07 GMT
Johndee Burks created HIVE-6009:
-----------------------------------

             Summary: 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)
