3 Different Time Zones in One Clock

İn this project I made a clock that shows 3 time zones(New york, Shanghai, Londra) in one clock.

I used ''Tinkercad'' for designing the clock.

First I made three cylinder outsides with different sizes. And I colored with colors of flag that country of the city. And I placed the clocks inside each other

I added a dc motor in the middle of the clock and I placed hour, and minute hands to the tip of the dc motor.

And I added gear wheels for the spin of the clock and changing at time zones
