Actually TIslandController doesn't have a current time. However, it 
utilizes its own event loop because there is so much concurrent 
interaction going on that it's easier to synchronize it by scheduling it 
via its own event loop. That event queue is entirely unrelated to the 
islands' queue.

That's exactly what the controller does. The TIsland needs its own 
notion of time though since it must be able to schedule internal future 
messages.
