Thanks for your feedback Lar,
I tried to do what you suggested, I initiated t1 inside the onRelease but the results stayed the same. Maybe I’m not following what you meant.

If you declare t1 ( t1 = getTimer(); ) in the onRelease method the results are different from just having it in the interval function. It was much closer to 1 second if the t1 timer was set in the initial release. When run as is the swf generated 1056 aas an average on my machine, when I declared t1 in the onRelease in addition to the interval function I was averaging 1000 – 1013. So the only difference is the t1 being set and not causign the NaN result on the first pass. Not sure what this means for your testing but thought I would share my results.

Thanks for your comment maliboo.
As I raise the fps it gets more accurate and at 120 it’s pretty good, but I can’t run most of my stuff at such high fps.

Try increase framerate (ieg 120). Also some framerates are “better” than others: my diff. 1000 interval on 30FPS was about 12ms, but for 31FPS it was ~24ms.
Interval isn’t executed in separate thread, but AFTER time, and code…

//—code
function a (when)
{
trace(getTimer()-when)
clearInterval(_root.i)
}

_root.i = setInterval(a, 1, getTimer())
var j = 100000; //the switch to 10
while(j–){};

Thanx for your comments momo

The time interval on my computer is not accurate as well.
I got Falsh MX 2004 and Player 8.
When I checked with 500 ms I got 550, 562, 544, 548, 561, 531, 558 …
When I checked with 1000 ms I got 1080, 1016, 1000, 1092, 1008, 1000 …
When I checked with 2000 ms I got 2015, 2014, 2000, 2000, 2000, 2000 …
It was stable on 2000 for a while.
When I checked with 2020 ms and it wasn’t stable.
(always higher than the Interval I wrote).
