Oh My God!!!
Just checked the family interface after last post, and it is true, Microsoft have indeed made it worse yet again. This is freaking ridiculous, they are making the family safety more and more useless with each change.
As Mark said, you no longer have any control of what times they can use the computer, you can set 1 time and that is all. The previous method was far better.
The people who are in charge of family safety clearly do not have children and know about them, which frankly is just incompetent to put such people in charge of such a project. So now we have Windows phones with no parental controls at all, and windows computers with less control than than they had before.
So far this is looking like Windows 10 is going to be a bigger FUBAR than Windows 8 was.
