>
> Hive recently moved its processing to the proleptic calendar, which has
> created some issues for users who have dates before 1580 AD.
> I'd propose extending the column vectors for times & dates to encode which
> calendar they are using.
> * create DateColumnVector that extends LongColumnVector
> * add a method to change calendars to both DateColumnVector and
> TimestampColumnVector.
> {code}
> /**
> * Change the calendar to or from proleptic. If the new and old values of
> the flag are the
> * same, nothing is done.
> * useProleptic - set the flag for the proleptic calendar
> * updateData - change the data to match the new value of the flag.
> */
> void changeCalendar(useProleptic: boolean, updateData: boolean);
> /**
> * Detect whether this data is using the proleptic calendar.
> */
> boolean usingProlepticCalendar();
> {code}
