What is the difference between physical and logical clock in synchronisation?
For many appls: ‰ it is sufficient that all machines agree on the same time. ‰ it is not essential that this time also agree with the real time E.g. make example - it is adequate that all machines agree that it is 10:00 even if it is really 10:02. Meaning: it is the internal consistency of the clocks that matters, not whether they are particularly close to the real time. For these algorithms it is conventional to speak of the clocks as logical clocks. „ Counter-ex: when the additional constraint is present that the clocks „ must not only be the same, „ but also must not deviate from the real time by more than a certain amount, the clocks are called physical clocks.

What is a leap minute?
A Leap Minute is a minute that is added or removed according to what's needed to keep our clocks and calendars in synch with the movement of our planet and the sun. The movement of the Earth around the Sun, and around its own axis, doesn't match up exactly to our clocks and calendars. To prevent the error from growing year after year, Leap days, leap hours, leap minutes, even leap seconds, are regularly added to keep everything in synch.

What regulates the length of one day?
The answer is surprising. Historically, it is hard to avoid the fact that a day is defined by the apparent movement of the sun. However today, because there are measurable changes in the earth's movements, the day is regulated by extremely accurate clocks that keep time according to a defined and unchanging second. Cesium clocks (or perhaps an even more highly developed technology) are actually regulating our modern concept of day.
