Review comment:
The Java ORC writer uses local time zone by default. However, the C++
ORC writer uses GMT by default in this
[fix](https://github.com/apache/orc/commit/8ea3592f6aeddb5e6930798e4ff95065c6177e00).
I hard-coded it to GMT at that time to work around the insufficient support of
timezone conversion on the C++ side. I'd suggest to leave some comments to
explain this history.
