Marc,
Thanks for the example.
When I ran it, I got the following:
steve at steve-Satellite-L555D ~ $ js fib.js
js: uncaught JavaScript runtime exception: TypeError: Cannot find function real-time-milliseconds in object [object Object].
I'm running Gambit 4.6.7 on a 64-bit Linux Mint 14.
Steve

Yes. It is in the standard release of Gambit. You need to use the option "-target js" to gsc. For example:
% cat fib.scm
(declare
(standard-bindings)
(extended-bindings)
(not safe)
(fixnum)
(block)
)
(define (fib n)
(define (fib n)
(if (< n 2)
n
(+ (fib (- n 1))
(fib (- n 2)))))
(fib n))
(define start (real-time-milliseconds))
(println (fib 30))
(define end (real-time-milliseconds))
(println (- end start))
% gsc -c -target js fib.scm
% js fib.js
