What goes in the timestep parameter?

[SQLSourcerer]

The example in the readme has a constant going in the timestep parameter, but for that matter, it also has a constant going into the y parameter, which is not how this component would actually be used.

A more illustrative example would be helpful.

Through experimentation, it seems like dropping in the current number of milliseconds elapsed time since the program started works better than putting in my other guess, a constant for avg ms per loop iteration. But I don't really understand why, or if I'm using that as intended
