Result may error when ORC load negative decimal value
When load negative decimal which has pre zero , the result is wrong.
eg -0.0014, the orc result is -14(precision ... 0)
The timestamp value load from orc file is error, the value has an offset with hive and spark.
Becuase the time zone of orc's timestamp is stored inside orc's stripe information, so the timestamp obtained here is an offset timestamp, so parse timestamp with UTC is actual datetime literal.
