I have here a big World Time Clock, known in German as Weltzeituhr. If you visit Alexanderplatz or Alexander Square in Berlin, you will surely see this clock. This square is quite interesting and you can always see a lot of people walking around there. It is located near the Fernsehturm or Television Tower.
Alexanderplatz is a large public square and transport hub in the central Mitte district of Berlin, near the Fernsehturm.
