- There are a couple of stream-oriented languages you should check out:
- Lucid, which I think was first developed at SRI, and SIGNAL, developed at
- INRIA, France by Benveniste, Le Guernic, and others.

- Given this, you'll be more interested in the SIGNAL work, I think, which
- deals quite a bit with different time bases and how to determine whether
- systems with different time bases are consistent.
