You can convert dates to characters using the TO_CHAR() function as shown in the following examples:

SELECT TO_CHAR(SYSDATE, 'HH:MI:SS') FROM DUAL;
04:49:49

SELECT TO_CHAR(SYSDATE, 'HH24:MI:SS.FF') FROM DUAL;
  -- Error: SYSDATE has no fractional seconds
  
SELECT TO_CHAR(SYSTIMESTAMP, 'HH24:MI:SS.FF9') FROM DUAL;
16:52:57.847000000                     

SELECT TO_CHAR(SYSDATE, 'SSSSS') FROM DUAL;
  -- Seconds past midnight
