Review Comment:
Yes, it's a little counter-intuitive because we only convert `secs[i]` only.
So, `Timezone.convertToUTC` doesn't care nanos part and we should not put it.
https://github.com/apache/orc/blob/f4c7cc14b31876e3dd4934b4bfc40c05d4b8ebca/c%2B%2B/src/Timezone.cc#L604-L606
If then, can we fix it in `Timezone.convertToUTC` instead? Is there a
side-effect?
