Digital Live Tile Clock app for Windows 8 Start Screen
Since there is no clock when the Start Menu is on, I have looked for a solution other than using the Charms Bar Clock. I finally found an app which satisfies my taste. It is a live tile clock which is very customizable, including a fairly wide range of colors.
For anyone who might want a clock on the Start Menu like I, try this one......Digital Live Tile Clock. Hope this helps someone looking in this particular area.
Update - I have found a more reliable store app - Ze Clock . It seems to be much more stable, in case anyone is still looking for a clock in the Start Menu.
