Simple UTC Clock for Mac
Here is a simple UTC clock for Mac. It was designed using FLTK and C++ as proof of concept during a cross platform GUI development exercise. Feel free to download and try it out. Currently developed and tested on macOS Mojave (10.14.5), but was compiled with -mmacosx-version-min=10.12 so 10.12 or later should be ok.
The clock installer can be downloaded here. If you have any feedback just send a message via the Contact page.
