keyTimes
O atributo keyTimes representa uma lista de valores de tempo usados para controlar o ritmo da animação. Cada valor corresponde a um valor na lista de atributos values e define quando o valor é usado na animação. Cada valor de tempo na lista keyTimes é especificado como um valor de ponto flutuante entre 0 e 1 (inclusive), representando um deslocamento proporcional na duração do elemento de animação.
Four elements are using this attribute: <animate>, <animateColor>, <animateMotion>, and <animateTransform>

Usage notes
The value of the keyTimes attribute is a semicolon-separated list of values.
There must be exactly as many values in the keyTimes list as in the values list.
Each successive time value must be greater than or equal to the preceding time value.
The keyTimes list semantics depends upon the interpolation mode:
- For linear and spline animation, the first time value in the list must be 0, and the last time value in the list must be
1. The key time associated with each value defines when the value is set; values are interpolated between the key times. - For discrete animation, the first time value in the list must be
0. The time associated with each value defines when the value is set; the animation function uses that value until the next time defined in the list.
If the calcMode attribute is set to paced, the keyTimes attribute is ignored.
If the duration of the animation is indefinite, any keyTimes specification will be ignored.
