Good point, as I have messed up with this before. But no I did run with `--enable-tuning=true` as you can confirm with the maximum time step size of 5.0 days...

Bug or feature is in the eyes of the beholder, as they say. I think this is a feature rather than a bug as it saves the user a bit...

Rather than a warning we should fix the case issue instead, so that it works as intended.
