How to stop/pause/remove the game timer in games using a Cube 2 Sauerbraten engine?

I enjoy playing Banana Bread, and now am working on learning to edit and make my own maps. But with a 10 minute game timer, there’s not a whole lot of time to make a ton of changes. Since Banana Bread uses a Cube 2 Sauerbraten engine, and can be controlled rather precisely if you know the correct command, I’m pretty sure there’s a way to fix this. I just haven’t found it yet, but maybe you have.

How can I stop/pause/remove the game timer games using a Cube 2 Sauerbraten engine?

What I mean by this is that after the timer would normally end, it instead keeps going and will allow me to edit the maps longer than normal. Ideal answer has a command I can type in or set of steps to accomplish this without downloading anything(I am on chromebook). Thanks!
