Password change minimum age

Hi team,

In our 12.1.0.2 database we have setup new password profile for new database accounts where user cannot change password more than once during a day.

I have enforced that by using adding password verify function to the database profile. Function looks like this:

CREATE OR REPLACE function SYS.ora12c_strong_verify_24h

(username varchar2,

 password varchar2,

 old_password varchar2)

return boolean IS

  differ integer;

  last_change sys.user$.ptime%type;

  minimum_age number :=1;

begin

  if not ora_complexity_check(password, chars => 8, upper => 1, lower => 1,

              digit => 1, special => 1) then

   return(false);

  end if;

  -- Check if the password differs from the previous password by at least
