Time type addition error

What I did:
There was a problem with the addition of TIME types when adding a time to another time and the result exceeded the 24-hour format. The result of the TIME type was not accurate.
An error occurred when '23:59:59' + TIME '00:01:00' was calculated.

CREATE TABLE t1(

c1 TIME

);

INSERT INTO t1 (c1) VALUES

('00:00:01'),

('23:59:59'); 

SELECT c1 + TIME '00:01:00' < TIME '01:00:00'

FROM t1;

What I wanted to happen:
The SELECT statement should return ((1,), (0,)).

What actually happened:
The SELECT statement actually returned ((1,), (1,)).
