> Currently getTimestampValue casts Timestamp to Date and returns Date.
> Hive Timestamp type stores time with nanosecond precision.
> Timestamp class has getNanos method to extract nanoseconds.
> Date class has getTime method which returns unix time in milliseconds.
> So, it order to be able to get nanoseconds from Timestamp fields
> GenericUDF.getTimestampValue should return Timestamp instead of Date.
