Tim May:
        I don't have a comprehensive theory of time, 
        but I am very fond of  "causal time."
Sometimes we read papers saying there is now
experimental evidence that quantum phenomena
are "a-causal" or "non-causal" or  "out-of-time". 
See, in example, these recent papers
http://arxiv.org/abs/quant-ph/0110124
http://arxiv.org/abs/quant-ph/0201036
Now, can lattices capture also those important
features?
