I wanted to stop thinking about and doing the small mental math around time zones.  I work remotely out of Idaho, my team that reports to me live in AZ, and my peers and boss live in Texas.  

So, I order these clocks off of Amazon for $12 which comes in a pack of 3. 

Then I 3d printed these stands and made them so that they could connect.  I made it so you can connect more than 3 if you want.  

Lastly, I just 3d printed these states and I was done.  I am super happy with my creation and am enjoying it.    

I made the design through Tinkercad and made the design public so that you can modify it more easily to fit your needs.
