Nous pouvons utiliser l'arithmétique pour manipuler les dates et la simple astuce CONNECT BY pour générer un flux de lignes.
alter session set nls_date_format='dd-mon-yyyy hh24:mi'
/
with cte as ( select trunc(sysdate) as start_date from dual )
select start_date + ((level-1)/(24*60)) as date_w_mins
from cte
connect by level <= (24*60)
