All differential equations require a delay to solve them - either z-1 in digital or s-1 in analogue (often an integrator but can be a sample and hold)

I was wondering if anyone knows any ODEs which generate a signal with harmonics which are progressively stretched? Meaning higher partials are further apart.
Or alternatively progressively contracted - higher partials are closer together.
Are ODEs the only kind of differential equation that can be solved without a delay line?
