Github user jcamachor commented on the issue:

    @omalley , it seems like a good idea, let me explore it and refresh the PR. I will adapt
HIVE-19226 to these new changes too.
    @wgtmac , I understand you are suggesting that this can be fixed only from Hive side?
Problem is that existing ORC files should still be read properly, hence you would need to
recognize old vs new ORC files. In addition, you will apply displacement twice when reading/writing,
in Hive and in ORC. It seems to me the cleaner solution is just being able to point to ORC
that timestamp data is in UTC from Java reader/writer. FWIW, change to stringify in TimestampColumnVector
is needed indeed.
