Stupid question about default time value

I made a table such as:

create teble x(
i int2,
d date default 'today',
t time default 'now',
dt datetime default 'now'
);

So these default values are not working as i think... they make the default
values to be equal to time when table was created....

i fixed problem in this way:
create teble x(
i int2,
d date default date( now() ), // or now() ::
date
t time default datetime_time(datetime (now ()) ),
dt datetime default now()
);

is there better way to do this?????
