strange overlaps?

Hello,

it's true?

tarif=# select ('10:10:10'::time,'10min'::interval) overlaps
('18:00:00'::time, '6hours'::interval);
overlaps
----------
t
(1 row)

I think not. There is problem in overflow one parametr.

tarif=# select ('06:10:10'::time,'1min'::interval) overlaps
('18:00:00'::time, '5hours 59min'::interval);
overlaps
----------
f
(1 row)

tarif=# select version();
version
