Review Comment:
I've attached here the `TreeReaderFactory` snippet that shows how UTC flag
is passed to the column vector. So your statement is not valid
> The PR approach works with existing way how TimestampTreeReader sets isUTC
flag in TimestampColumnVector
Please apply the suggested changes to get the fix in until the orc fix is
released. Note: now you'll have to cherry-pick the fix into the 4.1 branch
