Why we might never have a perfect clock



Every year, the time comes again when many of us change hours from summer or summer time back to winter. And confusion usually arises, is it one hour forward or backward? Why do we need to change time at all? Indeed, EU member states have been asked whether they only want to spend summer time.

Historically, the sun has helped us determine time – but we always have to make corrections to our reading so that it becomes effective.

The reason we have summer time, for example, is the amount of daytime is inconsistent throughout the year – different in winter and in summer – and does not always match our workday. But how do you manage time to develop throughout history and how well can it happen?

All year long the day changes, as does the location where the sun rises and sets on the horizon. There are also variations in location and altitude of the sun for a day, with peak height indicating that the sun is midday.

Knowledge of these markers helps humans create the first sundial that tells time (by tracking shadows on buttons) thousands of years ago.
