   ### What problem does this PR solve?
   
   Issue Number: close #xxx
   
   Related PR: #xxx
   
   Problem Summary:
   
   sometimes in join we need to do conjunctions for an empty block. that needs 
a default row. but for the current default value (`0000-01-01`) for datelike 
types, it may causea  false alarm for date functions. change the default value 
to make it harder to occur.
   
   before:
   ```sql
   mysql> select * from testdt_l where not exists (select f1 from testdt_r 
where testdt_l.f2 = testdt_r.f2 and (date_sub(testdt_l.f2, interval 8 
hour)=testdt_r.f2 or date_sub(testdt_l.f2, interval 16 hour)=testdt_r.f2));
   ERROR 1105 (HY000): errCode = 2, detailMessage = (10.16.10.3)[E-218][E-218] 
Operation hours_add 0 8 out of range
   ```
   
   now:
   ```sql
   mysql> select * from testdt_l where not exists (select f1 from testdt_r 
where testdt_l.f2 = testdt_r.f2 and (date_sub(testdt_l.f2, interval 8 
hour)=testdt_r.f2 or date_sub(testdt_l.f2, interval 16 hour)=testdt_r.f2));
   +------+---------------------+
   | f1   | f2                  |
   +------+---------------------+
   |    1 | 2025-11-21 00:00:00 |
