coba ini,
ALTER SESSION SET NLS_DATE_FORMAT = 'MM/DD HH AM';
SELECT to_date('12/31/2017', 'MM/DD/YYYY') + (FLOOR(rownum/24) + (MOD(rownum-1, 24)/24)) dt
FROM DUAL
CONNECT BY rownum <= ((to_date('01/02/2018', 'MM/DD/YYYY')+(1/23)) - to_date('12/31/2017', 'MM/DD/YYYY') + (MOD(rownum, 24)/24)) * 24

Jika Anda ingin menentukan jam mulai dan jam akhir, gunakan kueri di bawah ini, saya baru saja memodifikasi klausa CONNECT BY dan ORDER BY dari kueri pertama saya.
SELECT to_date('12/31/2017 10:00 PM', 'MM/DD/YYYY HH:MI AM') + (FLOOR(rownum/24) + (MOD(rownum-1, 24)/24)) dt
FROM DUAL
CONNECT BY rownum <= CEIL(((to_date('01/01/2018 02:00 AM', 'MM/DD/YYYY HH:MI AM') - to_date('12/31/2017 10:00 PM', 'MM/DD/YYYY HH:MI AM')) * 24))+1
ORDER BY rownum;
