    Description

      ORC timestamp writer stores the number of trailing zeros in 3 LSB bits. There is a bug in parsing nanosecond logic that returns incorrect value.

      Input:
      1999-01-01 00:00:00.999999999

      Output:
      1999-01-01 00:00:00.463129087

      The fix for this is parseNanos() should first right shift by 3 and then typecast to int.
