Why will we probably never have a perfect watch?



Every year comes the time when many of us change our clocks from summer or summer to winter time. And the usual confusion sets in, is it an hour before or back? Why do we have to change the time? In fact, the EU member states were asked if they would simply skip summer time.

The sun used to tell us the time – but we always had to make corrections to our readings to be effective.

The reason why we have summer time is, for example, that the daylight time is not constant throughout the year – it differs in winter from that in summer ̵

1; and does not always correspond to our working days. But how has the time history evolved throughout history and how well can it be?

As the year progresses, so does the length of the days, as do the places where the sun rises and sets on the horizon. There are also variations in the position and height of the sun during a day, with the peak height indicating noon.

The knowledge of these markers helped people to create the first sundials that determine the time (by tracking shadows on the dial) thousands of hours from years ago.
