Update all instances of a class with a single funtion?

[Amleto]

I think I'd probably make the vector of timer pointers a static member of the timer class itself, most likely a private one. The "update all timers" function would then be a (public) static member of that class as well. And timer objects would register themselves in their constructor. That way the whole thing would be pretty self-contained...

in effect, that's a singleton then ...
