In other words:

When the slider is from 0.000 to 1.000, how many seconds does it take to get from 0.000 to 1.000?

that depends on your cpu power.

But i have to bounce someone else will take over you.

It depends on your fps. (ie 25 fps is 4 seconds of video).

Common sense.

This is gh irrelevant. Please stick to gh questions.

sorry, I thought it is gh relevant!

its ok.

FPS =frame per second

after the animation is finished, hence you have a series of stills you get them into an animation program ie.after effects. there you choose the fps of you video or .gif ect ect...

so the final running time of your animation depends on this value.

Can't I just assume that the number slider, that I'd like to animate, is the time?!

It's like you'll have and flip book with 100 pages.

The duration of your animation depends on how fast you flip it.

if you animate a slider from 0 to 1 and make the frame count = 100

if you animate a slider from 0 to 1 and make the frame count = 200

if you animate a slider from 0 to 1 and make the frame count = 300

if you animate a slider from 0 to 1 and make the frame count = 400

Doesn't this has to do anything with the time? with seconds?

http://en.wikipedia.org/wiki/Frames_per_second

There is not a direct connection between the number of frames and the length of the final animation. Like the other posters have said, it all has to do with the number of frames per second. If your frame count is 100 and you show 10 frames per second, your animation will be 10 seconds long. If you show 20 frames per second, your animation will be 5 seconds long. 

A good standard is 30 frames per second if you want to avoid any jittery movement from frame to frame. So, let's say you want your movie to last 10 seconds long and you use 30 frames per second. How many frames should you tell grasshopper to generate? 10 x 30 = 300 frames. 

When doing animations, it's best to work backwards from the desired length of the animation and the desired FPS to figure out how many frames you need.
