You should be able to copy-paste time

Yes, that's exactly what I think now. It's 4:29am, and I am so happy copying things from my HD to CDs, reviewing my old short-stories, surfing the net and just being solitary, but not lonely. However, I'm going out to have lunch with my granpa tomorrow, so I should think of going to bed right now. Then, after lunch, I will have some 3 hours I really won't be doing anything at all... so why cannot I copy-paste those hours to give me more time to enjoy now? Ah, we need an Einstein, but with an engineering degree. I'm sure he (ok, also she :) would make it possible.
