What about a StepReactor?
It would be great to be able to stop time, have a means to look at the event queue and to say "DispatchNextEvent" by hand. Or even better, "PushTimeForward(x)" and see what happens. In short, a simulator.
This assuming, of course, that all other parts of the system are pausable, be they internal or external.

Is reactor.iterate[1] sufficient for this?

Well, it does not stop time, and also calls runUntilCurrent. I guess one should come up with a substitute for time.time in t.i.base (at least), that would allow to manipulate (fake) time at will.
Also, some means to display the event queue is needed, including the delays for each event.
Come to think of it, is there a way in Twisted to schedule an event at an absolute time, instead of at a relative one?

Sure.
reactor.callLater(desiredTime - time.time(), func)
:-).
The reactor stores DelayedCalls with absolute times instead of relative ones internally. The callLater API accepts relative times because that's generally the most useful to work with.

Of course. :^)

That's good to know.

Very true, and arguably there's no point in coming up with some convention to specify absolute time, since the above syntax is clear enough.
