---------------------------------
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.
