Great feedback! I'm considering that as well, to try the inner clock with numbers. The main idea of letters is to help distinguishing global time (UTC) from local time. So let's meet at 11:00 is local, and let's meet at M:00 is global. I'll try the numbers and test what would be simpler to use for users. Thanks!
