Bitcoin Block Time

[badboyrazor]

How do I find out the exact block time for BTC? I know its supposed to be every 10 minutes but what is the exact time to generate a block currently? Is there a website that has that information?

Block times are random, by design. To "find a block," a miner must set the nonce in the block header to a value such that, when hashed with sha256, the value of the block's hash is under the current difficulty target. This is done by selecting a random nonce to begin, hashing it, and if that fails, increment the nonce and repeat.

Due to the collision resistant properties of sha256, there is no way to predict whether any particular nonce will yield a block hash the meets the difficulty targey, and thus there is no way to predict future block times.

http://blockchain.info has the latest block times on the front page.  If you use bitcoin core, you can also ask for block information in the console for any block in the chain, as each has a timestamp of when it was found.  As for future block times, one can only say it's an average of every 10 minutes.

I prefer to use http://bitcointicker.co/networkstats/ not only has that information but a lot more that is useful, bitcoin blocks on average are created every 10 minutes but there are blocks that are generated faster and some that are generated more slowly.

no, the time between blocks is not supposed to be 10 minutes, it happens to be 10 minutes most of the times or on average.
what it should be is that the number of blocks in one difficulty period should be a fixed number: 2016 and we want it to take 2 weeks to find that number of blocks. https://en.bitcoin.it/wiki/Difficulty
