We should also change writeBatch function below.
The input vector.isUTC may be true while writer.isUseUTCTimestamp() is
false; vice versa. In this case, we need to convert them to correct writer

> Key: ORC-341
> URL: https://issues.apache.org/jira/browse/ORC-341
> Project: ORC
> Issue Type: Improvement
> Reporter: Jesus Camacho Rodriguez
> Priority: Major
>
> Currently, time zone is hardcoded as the system default time zone and ORC
> applies displacement between timestamp values read/written based on time zone.
> This issue aims at adding the option to pass the time zone as a parameter to
> the reader/writer.
