This is a great idea as I was just thinking that it would be nice to have the time on the Start Screen.
However, it appears not much thought was put into this. Come on Stardock, we know you can do better.
1. Give users the option to choose between 24 hour or 12 hour.
2. Give users the option to choose size, color and location as some peoples backgrounds (if a busy one or really light colored one) may not blend well with the utter small'ness of the clock.
3. The option to have it display as a tile or separately like it is currently.
4. The option to display just the hour and minutes or add seconds as well (though I wouldn't want to see seconds some people may).
