I've never done it myself, but you can move the build tick with the Quartermaster in the keep. However, it requires for you to have met upkeep. I think you need to interact with the Quartermaster when you want the build tick to occur, it's in the right click option. Also, the citadel 7 days timer only starts once someone visits the citadel, which is why your reset time changed so much.
