Script to move layer back and forward in time (After Effects)

[johnt53984649]

In After Effects, suppose I have a layer with keyframes and I want to move its position in time. I can't just set it using 

myLayer.startTime = new_start_time

because that doesn't move the keyframes along with it.  I essentially want the exact same effect as dragging a layer to the left or right (as you would in the GUI) but with scripting: You can see what I mean here: https://imgur.com/qpIilCw

How do I move a layer and its keyframes with scripting?

Well, not sure how this isn't working for you, because it does work as expected - layer.startTime does move layer and its keyframes to a new time.

You are correct, I apologize. It turns out I had a bug in my script that was leading me astray.
