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? s.
