There are related questions with some good answers. The answer depends on the type of spider. Some spiders that build orderly webs can do so in 15-20 minutes or so. Others take longer. Many don't build orderly webs and they work on their webs from time to time. some build a new web every day. Others don't. You're probably thinking of an "orb"-type web when you ask the question. One related question elicited an answer of less than an hour. I've seen them done in significantly less than that, but i bet that's a good upper limit. Some spiders do not build webs at all.
