---------------------------------

             Summary: currrent_timestamp in ISO-SQL is a timezone bearing type but Hive uses
timezoneless types
                 Key: HIVE-11377
                 URL: https://issues.apache.org/jira/browse/HIVE-11377
             Project: Hive
          Issue Type: Bug
          Components: Documentation, SQL
    Affects Versions: 1.2.0
            Reporter: N Campbell
            Priority: Minor


Hive 1.2.x has added the niladic function current_timestamp. when ISO SQL introduced time
zone bearing types, it defined two forms of niladic functions. Current_timetstamp/time return
time zone bearing type and Local_timestamp/time non-time zone bearing types.

This implementation is not described in the current documentation.
