Midnight UTC is zero's all the way down. Seems false to me, but I'm from the land of C. This seems to be in line with some low level hardware or common assembly practice across many languages. Everyone is talking higher echelons of consideration, but what effect is there on generated byte code or in fitting within the virtual machine's tight pants?
