Very quickly and especially since you are starting with kiln dried lumber. Hard to give it to you in hours and minutes since temperature, humidity, sun exposure, moisture content of the wood and all will play a role. You might look up the data sheet on whatever you get to see what it says. Can label may have it also.
Just a comment and I sailed boats with natural grayed teak decks so do not mind the look. Are you sure you want to do this to nice kiln dried cedar though? Just asking and double checking, not judging, I promise. Trimmed out with slick looking railings and so forth I am sure it will look great. This is not a set it and forget it proposition though. You are still going to have to use something on the deck every few years depending on climate.
