> ORC PPD evaluation for Date type uses java.sql.Date for min/max comparison.
> Date.compareTo uses millis offset which can return incorrect results depending on the timezone. 
> Running the testcase in HIVE-19726 passed in Los Angeles but failed in Paris as Date.compareTo return 0 for Los Angeles but returned -1 for Paris. 
> Similar to bloomfilter, min/max evaluation should use DateWritable (as DateWritable.compareTo uses days offset).
