Time difference without intervals

I saw this question on another PG mailing list, and I don't know how to
answer. I've tried casting the interval to a timestamp, but that doesn't
seem to be supported in 7.2. Does anyone have an answer?

Is there any way to make a timestamp difference operation not return an
interval? I'd like to get hours, minutes and seconds only, not the "1 day"
or whatnot.

lbn-dev=# select now() - '2002-11-07 7:42'::timestamp;
?column?
-----------------------
1 day 02:01:57.987838
(1 row)

Thanks,

-Roberto
