As opposed to automatic adaptive timestepping, to allow the timestep to change over a pre-defined period the run (e.g. 60s for first hour, then 360s). This would reduce differences in results for similar models, observed due to time-dependency (e.g. with reservoir volumes).

I tend to think models shouldn't be timestep dependent! Are there rules in the model which operate at funny times? Those can cause differences when the timestep is changed.
Otherwise, surely any differences should be so small as to be insignificant?

That said, if it's a problem, fixed timstep is there...
