In the "References" section of Bitcoin's whitepaper, Satoshi Nakamoto points to three papers that serve as inspiration for digital timestamping.

When you read those documents it is clear that timestamping is not just a stamp of time, but "the hashed value of [data + timestamp]".

That said, in Bitcoin, is the timestamp the hashed value of the block header vs. the just time in the blockheader?

Or, am I totally off base?
