Ryan Blue commented on ORC-189:
-------------------------------

The Hive issue says Druid needs timestamp or [timestamp with local time 
zone|[https://docs.oracle.com/database/121/SUTIL/GUID-CB5D2124-D9AE-4C71-A83D-DFE071FE3542.htm].]
 That includes a zone offset, which isn't required for timestamp with time 
zone, which is simply converted to UTC and then stored. Is timestamp with local 
time zone what was intended on that issue, and is that what will be added to 
ORC? ORC could represent both with the same format, but it would make little 
sense to store a zone offset for timestamp with time zone because it would 
always be UTC.
