> Currently {{TableResult#print()} simply use {{Object#toString()}} as the 
> string representation of the fields. This is not SQL compliant, because for 
> TIMESTAMP and TIMESTAMP_LZ, the string representation should be {{2021-02-23 
> 17:30:00}} instead of {{2021-02-23T17:30:00Z}}.
> Note: we may need to update {{PrintUtils#rowToString(Row)}} and also SQL 
> Client which invokes this method.
