Hmm ... there seems to be some confusion :|

This stuff is complex, and I don't understand your code.

The comment in your code

  <!-- move 20 units every second -->

seemed to state that the code tells your implementation at which frame
rate to play this animation. Playing it at 50fps instead of 20fps
would not be possible then.

If the code instead says "the animated object should be at 20 * x
units after x seconds, animate with any frame rate you like (redraw as
often as you like as long as ($current_position/20 ==
$seconds_passed))" then that's something else.
