I am looking to try and create a "Mars time" watch for my GTR 3 Pro. However, Mars time has a different length of day, equal to 24:37:22 earth hours per Mars day. Now - not surprisingly - I did not see any options in the tools for my GTR 3 Pro to make a face with a different length of day.
Are there any suggestions on how to do this? Do I need to dive down into what I think is more detailed scripting/programming to make this happen?

The editors don't allow you to do that. You need to write your own code to get the result you want.

That is sort of what I was expecting, unfortunately 
Thank you for the clarification.
Is there a possible hint - when you say "write your own code" is this the construction I see in some of the really capable watch faces, with specially written Javascript files (and .. PNG files that seem to be different and readable???), or is this more in the way of needing to create a whole ZeppOS application? Any build tool names that might be a starting point for research?

It all depends on what you want to get in the finished watch face. Most of the elements can be done in the editor. Then add code to the dial to display the time as you want. If you display it in text, it's easier. If it's a set of pictures, it's more complicated.

I found that I could modify the calculation code for the GTR 3 Pro specialized analog display, and so leverage the existing display of hands. The key was finding that the sensor API returns a standard "1970/1/1 epoch" value, which serves as a stable starting point for the calculation.

I couldn't understand why you use timeSensor.utc instead of the simpler timeSensor.second until I read the description of the watch face. Unusual watch face. I think creating this watch face was a good mental workout, but not many people will be interested in it.
If you want to modify the watch face longer I can recommend this idea. Swap the earth and mars. When you click on mars, switch between mars and the rest of the planets (and maybe the moon). I am not good at astronomy, so I don't know how relevant it is to calculate the time for the other planets or the moon.
