I like the idea of lazy evaluation via interpolation.  If I find
that such updates are a problem, I might steal this idea.

I suppose you need B if you have the player health always displayed.
But it seems rather unlikely to me that one would need to update
health on every tick, unless you have very low tick granularity in
the first place.

In my event system, there is just a tick timer that gets advanced.
I wouldn't bother checking the system clock, since that gets done
often enough already.  I'd just check my tick counter, and infer
time that way.  Seems fast enough.
