   > Your solution has a limitation - it doesn't handle structs, such as a 
StructColumnVector that includes a TimestampColumnVector among its fields.
   
   That can be easily fixed. Note that your solution assumes that ORC readers 
use exclusively `fileReader.readerOptions()` to set `isUTC` flag in 
`TimestampColumnVector` and this is not always the case (as you can see from 
https://github.com/apache/orc/pull/2300). Another issue with your PR is that 
all that propagation of `fileReader.readerOptions()` to `RecordReaderImpl` is 
not necessary (obsolete) once https://github.com/apache/orc/pull/2300 is fixed.
