JDBC gives inconsistent date values for their years 1600 or below

[njmarshall]

To reproduce the issue

1. Create a table and populate two dates including years of 1500 and 1600 on MAPDQL
   CREATE TABLE t_date(id SMALLINT, val DATE);
   INSERT INTO t_date VALUES(1, '1500-01-01');
   INSERT INTO t_date VALUES(2, '1600-01-01');

2. Run the SQL stmt against MAPD
   SELECT * FROM t_date ORDER BY id;

3. Run the SQL stmt against MAPD thru JDBC
   SELECT * FROM t_date ORDER BY id;

Data Results from No. 2

id|val
1|1500-01-01
2|1600-01-01

Data Results from No. 3

id|val
1|1499-12-23
2|1600-01-01

Explanation

Noticeably, JDBC displaying the date for the row 1 is not the same as MAPD. JDBC displays "1499-12-23" as supposedly matched with "1500-01-01" from MAPD DB. Does this difference tell JDBC doing date validation than MAPD?

According to NOSQL's document, the range for the Date datatype is from 1000-01-01 to 9999-12-31. Is that correct?

@dwayneberry Do you think the JDBC functionality for datatype displays should be identical to MAPD?

@njmarshall we are in the weeds here. Are you familiar with the 'Council of Trent'. The calendar under went modifications in this time period to readjust.

Sorry didn't mean to close it.

I'm not sure where we would stand regarding UTC to pre "Council of Trent" definitely a conversation to be had over a beer :-)

Yes, my purpose is to find anything necessary to be fixed, improved or upgraded for rising a level of the software quality.
