The time of the day at the start should be random.

I agree that the time of day should be changed, but I don't know if I would say it goes against the Undead. I've often thought that on most maps, it favors chaotic forces, because even if the scouts start fighting on the first few turns, the major engagement is going to be around turn 4, just as it is getting dark.

Of course, this also depends on starting gold and village gold. If you have low for the first and high for the second, your scouts are more important because grabbing villages is more valuable. Thus, lawful units are favored. If you have high starting gold and villages only generate one gp, the chaotic forces are favored because villages aren't important and it is the clash of the main armies that is going to be at night.
