Tazz V. Chakramaster: Round 3. We all knew it would happen.

I believe Neo actually outright said it does not change anything at all except for the flavor text of searching at night (IE requiring lights to see properly), which, I might note, is basically all your proof contains. I believe his word on this (as requested by Sacred Fire) would be far more informative than either of our figurings on it, though. I mean, clearly there are other things the Day/Night cycle changes, but this isn't one of them, to my knowledge.
