Play and pause multiple timelines at the same time

[BitBarrel]

I have two timelines (not state machines) on the same artboard.

I want to set one timeline instantly to the 30% position, don’t move it, keep it there.

Then I want to set another timeline instantly to the 20% position (while keeping the other timeline at the 30% position), don’t move it, keep it there too.

This is possible with the "advance" feature of the API. See the paragraph "Advancing Animations" here:
