Very cool, I have two suggestions for your mod:
1. Be able to change the time interval at which the time updates in the Factorio mod settings. (1/3/5/10/30/60 seconds for example).
2. Be able to change the rounding of the progress percentage in the Factorio mod settings. (if you're at 1/3 and your setting is 2 decimals, it'd show 0.33)
By the way, Xterm covered your mod! https://www.youtube.com/watch?v=lb2i8ofhKN8
