The arithmetic looks complete. The clock model is not.</p> <p>Civil time exists to place events on a shared calendar. It can be corrected to stay aligned with an external time reference. Elapsed-time measurement has a different requirement: later observations within one running system need an ordering suitable for measuring an interval. A clock correction that improves civil-time accuracy can therefore be harmful when the same reading is treated as a stopwatch.</p>
