How long do I let the liquid nails dry?

More questions on my shelf project. The shelves themselves are made of left over laminate wood flooring. They piece together by tongue and groove. I’m ready to glue each shelf together but I only have 3 clamps, and I plan to use all three per shelf. However, I have 6 shelves. If I wait 24 hours for the glue to dry, it’s going to be another week until I can finish. Bleh! I’ll do that if I have to, but can I wait less time that that to move on to the next one?
