This is on 2.2-960612-SNAP. I think you are misinterpeting the log entry. xtnpd works by adjusting the length of a 'tick' so the clock 'speeds up' or 'slows down' as necessary. This adjustment is called 'slew' and is inserted in very, very small increments. But time continues to move forward, even if it means slewing the ticks for quite a while.
