Insert date into Oracle

Here is my SQL Statement:

insert into AD.aracct_range (acct_range, acct_range_desc, login, log_date, log_time)
values ('b', 'not applicable', 'wang', to_date('05/21/2004', 'mm/dd/yyyy'), '14:24');

Is that any possible to insert date without using to_date function. Because my application currently migrate from Unify database to Oracle.

Thanks in Advance
