Unit issue in EvaluationTest1 and Differentiation2

Lines 4 to 7 in a8677a6

	Real yp;
	equation
	yf = Polynomial(time, {1, -2, 2});
	yp = time^2-2*time+2;

The equation yp = time^2-2*time+2 is questionable from a unit perspective, since it subtracts things with units s2 and s, which are not compatible units.

The same issue exists in the model Differentiation2.
