[Ktechlab-devel] Update rates

[Zoltan Padrah]

Yes. the logic update is done as you've written.

What do you mean by unstable? Ktechlab crashes or just outputs garbage?

Also I don't understand how to reproduce the problem. Set the logic update
timer to 5e6 and then?

Maybe Alan knows: how is the time in simulation managed? We should provide
the some ways to know what is the current time in the simulation, and how
much time has passed since the last step (for reactive elements).
