Actually, they're closer to this: https://commons.wikimedia.org/wiki/File:Tz_world_mp-color.svg although this isn't quite right either, e.g., for Ürümqi.
You cannot set /etc/localtime to a posix TZ string.
You can remove /etc/localtime, giving UTC in all implementations I know of. We could approximate this by having a new top-level selection for tzselect which acts like TZ='UTC0'. Although that wouldn't be quite the same thing, it might be good enough.
