Return the elapsed time (in seconds) at the specified control point index in the animation path. The time is dependent on the control point position/times and constant speed setting.
The time returned by this command can differ from the assigned control point time specified in the
<animationpath>.addControlPoint command. This can occur if the first control point time is not 0, or if the constant speed setting is enabled.
The current speed factor (
<animationpath>.setSpeed) is ignored.
