I'm ambivalent on the topic. Sure you can instill the values of proper time management into your kid and hope they abide by them when you're not around. However, I don't feel it's unreasonable to have an automated solution for this kind of thing. Just like I'd love to have automated lighting in my home, or automated curtains, or a computer that will automatically turn on at certain times, sometimes it's also nice to have a things that automatically turn off after a while as well.
