This mod allows for finer timescale adjustment and to stop time. With this mod it is possible to set a timescale of 0-1 in steps of 0.2, 0-15 in steps of one, from 15 to 30 in steps of 5 and above that in steps of 10 and 20 up to 240 and 40 up to 400 and from there to max 500.
With a timescale of "0" the time stops completely. This Mod also works in Multiplayer, the timescale can only be changed from the Host or somebody that is logged in as Admin.
The basic keybindings are CTRL + key 4 (down) and key 5 (up).
