Here's how :
SQL> create table job_table (job_name varchar2(50) not null, scheduled_time date);
Table created.
SQL> insert into job_table
  2  values ('Job_abc',to_date('25-JUL-2009 04:00:00','DD-MON-YYYY HH24:MI:SS'));
1 row created.
SQL> insert into job_table
  2  values ('Job_fdw',to_date('02-JUN-2009 04:15:40','DD-MON-YYYY HH24:MI:SS'));
1 row created.
SQL> insert into job_table
  2  values ('Job_fxj',to_date('27-JUL-2009 03:59:00','DD-MON-YYYY HH24:MI:SS'));
1 row created.
SQL> insert into job_table
  2  values ('Job_rjt',to_date('20-JUL-2009 14:59:00','DD-MON-YYYY HH24:MI:SS'));
1 row created.
SQL> commit;
Commit complete.
SQL> alter session set nls_date_format='DD-MON-YYYY HH:MI:SS AM';
Session altered.
SQL> select job_name, scheduled_time from job_table
  2  order by to_char(scheduled_time,'HH24:MI:SS');
JOB_NAME                                           SCHEDULED_TIME
Job_fxj                                            27-JUL-2009 03:59:00 AM
Job_abc                                            25-JUL-2009 04:00:00 AM
Job_fdw                                            02-JUN-2009 04:15:40 AM
