Re: The timeline of MoS
They definitely fudged the aging about in he movie. Zod even says that they had searched for Kal for 30 years when they received the beacon from the scout ship. They could have avoided the whole issue if the would have just had Zod and crew awakened on schedule and have it be 20 years after the destruction of Krypton. Not a major issue either way considering they are aliens and who knows if they age like humans either way.
I wish the amount of time that elapsed after we get to Earth was a little clearer. The movie is edited so tightly that it makes it all feel rushed.
