I don't see how Aliens contradict anything that Alien did. Aliens never showed us exactly how long was it between the time the first colonist got facehugged to when the Marines arrived there. And since in between the trip, the Marines had to undergo cryogenic hibernation (freezes the body, allowing them to survive for a long time), I'd probably say it was alot more than 24 hours.
