More informative parameter name or javadoc for QueryParameterValue#timestamp #2709
Description
The method QueryParameterValue#timestamp doesn't give a code author a clue what kind of value is expected there.
It might be considered 'common knowledge' that BigQuery works with epoch microseconds here, but it would still be nice to give a hint here, either by using the paramter name epochMicros or giving a hint in the javadoc.
Thanks
