It is usual, but not universal, for the DC+ to be the centre pin of a circular DC power connector, and I believe that's the case on the Timestep, but do check with a multimeter and be quite sure. There is no right or wrong here - as long as you know which way round the +ve and -ve go in your PSU and connect the deck up to the DC connector correctly, then all will be well.
