No, I can't afford the book and the public library here seems to spend most of its money on celko books. I could read the whole book at the university library but they won't let me borrow it and I wouldn't appreciate it properly as they won't let smoke in their building. Whereas I am allowed to have a fag in the kitchen where I read this group. So my excuse is that poverty and addiction keep me out of the higher realms of discussion.

However, one of the authors makes a few comments at:

http://en.wikipedia.org/wiki/Talk:Temporal_database

 From this I gather that their preferred operations operate on domains made only from intervals that are based on some practical measurement scale, not quantums nor chronons.
