Measuring ColumnarToRowExec execution time

Hello,
I wish to measure how long ColumnarToRowExec takes to execute. Currently
only 2 metrics seem to be captured i.e numOutputRows and numInputBatches.

I see that the RowToVeloxColumnar operator captures the "convertTime" and I
suspect that this convert time is capturing the conversion time for both
ColumnToRow and RowToColumnar due to the "iterator" nature of that code.

Is it correct to say that the "convertTime" metric of RowToVeloxCoumnar
also contains the conversion time for ColumnarToRowExec

Thanks in advance for your help.
