Quiz on the time change Since when has the clock been turned?

Daylight saving time has been in force again since Sunday. We have become accustomed to the clocks being changed twice a year - but do you know the background to this ritual?

The time change at the beginning and end of summer is as old as the controversy surrounding it. There are repeated calls for an end to this practice in Switzerland, and the situation is no different in other countries.

You can test your knowledge of how long the clock has been turned in Switzerland and elsewhere with this quiz. Have fun!
