Incorrect results with TIMESTAMPDIFF in JBEDS

Issue

• I am getting incorrect results when using TIMESTAMPDIFF in JBEDS:

select TIMESTAMPDIFF(SQL_TSI_DAY,parseDate('2012-01-01', 'yyyy-MM-dd'),parseDate('2304-04-12', 'yyyy-MM-dd'));

result = 106751

If you increase the end date by 1 day:

select TIMESTAMPDIFF(SQL_TSI_DAY,parseDate('2012-01-01', 'yyyy-MM-dd'),parseDate('2304-04-13', 'yyyy-MM-dd'))

result = -106751.  

I would expected the answer to be 106752
