You have to thank Luke-Jr (pool operator of our sacred Eligius, which put prayers in the blockchain for all our sins) for that shit
He deliberately put false timestamp because he wants one of his idea being accepted by the Bitcoin devs
A kind of blackmail

I have noticed that sometimes block timestamps appear out of order. For example:
>> 142884 2011-08-28 05:23:00 1 50 1805728.389 7144249.91789992 265.327 966.464 36.101%
>> 142883 2011-08-28 05:23:14 27 896.27036728 1805728.389 7144199.91789992 265.329 966.464 36.1009%
Block 142884 bears a timestamp which is 14 seconds earlier than the prior block.
I asked this question on #bitcoin-dev and got: https://en.bitcoin.it/wiki/Block_timestamp, which makes sense.
My question is: how can the network afford for the timestamp to be up to 2 hrs advanced? Does this open the door to any kind of time based attack on the network?
