The widget wasn't working, but then the creator figured out that the problem was a setting regarding battery optimisation. And now it works perfectly. So does this mean that it will be possible to add a second hand? Also, I would like to request an inverted-colour version, with white numbers on a black face.

This is a great app, i was interested in Decimal time, but can you include time in multiples of five ? 20 hours in a day, 50 minute in an hour and 50 seconds in a minute...would be really helpful if you include this format in the app

Good job. But I request that dozenal clock would be rotated 180 degree, to represent hour arrow being at the bottom as sun is down, and in mid day the hour arrow would be at the top.
