If you look at your itinerary, the time you will in port is listed, so, I would say maybe an hour or so &, you can get off In tendered ports, if you bought a ships tour, you get on the tenders first. You get a tender ticket,[they will announce where to pick them up] and wait till your number is called.
If it's not a tenedered port, just be on the gangway as early as you need to tour.
Trip, with her book & tea!
