    AFAIK, I don't think ORC has any issue in HIVE-12192. What ORC guarantees is that we should
always get same wall clock time representation w/o timezone. Current Java implementation leverages
java.sql.Timestamp which uses local timezone and that's why writer and reader always use 
timestamp values in local timezone. Unless we add a new TimestampColumnVector which enforces
UTC timezone to adopt your change here.
