×I started from the NE. Before stepping onto the time token, I stood north of it and fired a bubble south.
When recording, I waited one turn, moved south, waited four turns, and moved south again. That was the whole recording.
From there I bubbled as many chronovores as I could. The first time clone is the only hard part; if you get the chronovores in the right places, you can protect the second with bubbles and just wait in place.
