Can it really be simpler than now_diff/2?

loop(Timeout) when Timeout > 0 ->
    Before = now(),
        X ->
            % Do whatever
            loop(Timeout - timer:now_diff(now(), Before) div 1000)
    after Timeout ->
loop(_) ->

(If I needed millisecond precision I would do it a little different
just to be sure.)
