The processor's man task is calculating location and its firmware is dedicated to that; by the time it gets around to spitting out time-of-day info, the moment has passed. Even using the raw NMEA data can get you into trouble if you aren't clear about whether each sentence pertains to the second just passed, or the one coming up.
