Time moves at one constant. How can you have it raised to an exponent? If you have say: 3 seconds^2, is it actually 9 seconds?

No if you square units you have that unit twice. 3m² are an area and not 9m length.
Squared seconds rarely matter alone. But having something per squared second often makes sense. For example m/s² is meter per second per second (so speed per second, wich is how much you accelerate)
You can have more abstract variables that are of the unit s², not something “directly measurable” though. For example “length per acceleration” would be in s², and that might come up if you measure acceleration with a spring-mass system (the variable would then describe the measure sensitivity)
