Timestamp on 230939 predates that of 230938. The "Received Time" is later though.

There's no easy way to enforce a "correct" timestamp on blocks, so some variance is accepted.

(I guess some miners also use the timestamp as a nonce, and that means that if you can produce more than 232 hashes per second you'll likely mine on blocks with "distorted" timestamps)

They only used an int for the nonce?

Only 32 bits, yeah.
But the timestamp is also part of the header. And the miner can manipulate coinbase as he wants, what changes the Merkle Root which is also part of the header.
