Summary: TIMING_INFO gets time units mixed up

Initial Comment:
TIMER_INFO  gets units of time mixed up -- in the
example below, should show 0.25 seconds instead  of 25
seconds; setting TIMER_DEVALUE:TRUE before calling
FF(200) makes the time come out as 0.25 seconds as
expected.

Note that the time reported for GG is 25 seconds while
the time for FF is 0.25 seconds -- the two should be
identical or nearly so.

See also bug report #572835 ("timer_info gives
incorrect time").

Maxima 5.9.0 cvs version of 20031128, clisp 2.31,
redhat linux 7.1 (kernel 2.4.2).
