You could also look at the Bitcoin blockchain, e.g. on the blockchain.info web site. There is a new block generated every 10 minutes or so. Some useful fields in the block include the nonce (a 32-bit unsigned) or the block hash. You can set a target time and say that the first block generated on x-date (UTC) will be used. Blockchain.info and some others like it have a free API.
