I dont seem to find the information under Quest
It is eight hours. And you do not take physical control of the city. Just take a resource tribute and get to perform an additional levy after every maintenance. And you do not need to keep troops there. Just set your suppression settings and the rest is automatic. But you should keep them at 0 anyway as people have found ways to kill your army without attacking you.
