You'll need to get the syntax for PL/SQL function calls right. You will need something like
create or replace function whatever( arg datatype, arg datatype...) return varchar2 is
  --define any local variables here
begin
   return to_number(to_char(systimestamp,'the edit mask you want to use'));
end;
/You might do the conversion inline and dispense with the function compeletly if you're just generating a value.
