Is there a way to use a computer to hide information until a specific date? Perhaps some website that will do that (you upload a file and you can't download it before some time determined by the server clock).
Encrypt with the desidered UNIX time, decrypt using time().

That's trivial to break. I guess you could use NTP, but packets can be spoofed.

"Time" doesn't exist.
Clocks exist.

Centralized way: encrypt the file, place the key with a trusted entity that promises to release the key on a specific date. Since this isn't cool enough, use Shamir's Secret Sharing to split the key between multiple entities, to ensure their honesty. Congratulation, you wannabe-cypherpunk, you. insurance.aes256, anyone?
Decentralized way: you need a distributed trusted timestamp server. Though one, perhaps find a way to piggyback on bitcoin's blockchain?
