For printing Time, do not use Floats. E.g., '6:27:08.649' asTime was printed as '6:27:08.649000000000001 am' due to converting to floating point for printing, when the representation itself uses precise numbers (nanoseconds). This fix introduces Integer>>printOn:asFixedPoint: which might not be the best idea; if some other dialect has an existing method that does something similar we should use that selector.
