A spout that emits "ticks" at specified intervals would be useful for various time-oriented computations (e.g., rolling windows). This would make it easier to code bolts that do these time-oriented algorithms, since they won't have to worry about multi-threading and concurrency.

It might be better to put ClockSpout in storm-contrib.
