CZML Hide Model part

I would like to know how to instantly scale part of a model to zero using a CZML model articulation.

I may be doing something wrong, but it appears the smallest time period my transition can occur is over 1 second.

To test, I added the following articulation to the sandcastle example at:

“SRBs Size”: {
epoch: “2019-06-01T16:00:00Z”,
number: [0, 1, 10, 1, 11, 0],

I also reduced the clock multiplier to 1x so it will display the undesired behavior.

I was able to fix this by adding multiple of the same articulations with the fractional seconds in the subsequent sections. Updated the sandcastle:
