If you are DBA, how many hours per day in average you do actual work?

I sit next to a DBA and it can be really feast or famine for him. If there are patches to install or a failure of some sort he may work a 12 hour day. Other times he is just monitoring systems and reviewing performance reports, maybe 4 hours work. If he is involved with a development effort, then it is more engaging work and more of an 8 hour day.
