Using a PathAnimation, if I set the time value programtically, the time line jumps to the new time for an instant, but then immediately jumps back to the original elapsed time. I have tried this using in-flight change and by [pausing, set time, and play]. NB Project is attached.

Using the attached code the four right buttons do the following.

1) Skip Back - set time to 0ms
2) Seek Back - set time to -1s
3) Seek Forward - set time to +1s
4) Skip Forward - set time to end
