Currently Delta Client's sky is literally just a hardcoded clear colour for the MTKView which means that there isn't really much of an idea of time of day. There is also no sun/moon/stars rendering. Implementing rendering of the vanilla sky box would really make the client's rendering a lot more convincing. This task requires knowledge of Metal, transformation matrices and reading the decompiled Minecraft Java source code (not too difficult, I can walk you through decompiling it with a tool). This is definitely a non-trivial task but my guess is that it could be completed in less than a week with not that much work each day (less if you are the sort of person to spend many hours at a time).
