When I was a full-time student I viewed my PhD as a 9-5 job, so stuck to those hours. I'd get into work about 8.15, to get parked, then would surf the Internet (early days of it!) for a while before 9, then get started properly. Come 5pm I would leave.
My husband took the same approach when he started (and completed) a full-time PhD too.
Now of course later as a part-time PhD student (and successfully completed) I was, for much of the time, managing on no more than 5 hours total a week. Not to be recommended. But I don't believe people need to put in vast amounts of hours. A lot can be wasted procrastinating. A lot can be achieved in much less time.
