The method changes the clock rate (regulation) to have it run 'slow' if the clock is ahead, or 'fast' if its behind. If nothing else was then done later, this would mean it eventually overshoots and runs away. But you also choose to have system re-regulate at user-specified intervals. The amount by which the rate is regulated fast or slow is, I think, meant ot be affected by how much in advance or behind the clock may be. That then means that as the process is repeated the clock error *should* tend to get smaller and the regulation 'nudges' smaller. That should mean that an 'always on' system slowly glides toward having a small time error and a modest rate correction. The problem is that this may not work for various reasons, some of which are obscure. If you're going to test this, also note the times when the machine is switched on or off.
