... is an always visible time and date as we can do with the desktop Task Bar

Last night our kids went to bed 15 minutes late because while I was out for a run my wife was playing Wordament on out Win8 machine and she lost track of time -- mainly because there was no on-screen clock to remind her.

I've found apps to show the date and time on the start screen, but there is no provision for something that is always visible (you would have to use up a large amount of screen real-estate to show a docked app just to see the time).

Of course, I have no idea where you would display the time in a way that doesn't interfere with the Store App design.
