How long can an astronaut stay in a spacesuit?

Nominal duration of excursions in a pressure suit usually runs between 5 and 7 hours. It depends, of course, on the consumables available to the suit, such as oxygen, battery power, cooling water, etc. (spacesuits really being rudimentary spacecraft), but working in a suit is also quite strenuous, and so its use is also limited by the comfort level and endurance of its wearer.
