Tomorrow from 5 to 10pm at The Sycamore in San Francisco some friends and I will be accepting bitcoin payment for draft beer.

Regarding the mystery miner being discussed in https://bitcointalk.org/index.php?topic=67634.200 ... (originally at 88.6.216.9 and now at 85.214.124.168):

A little while ago they mined four blocks in the space of 1 hour:

http://blockchain.info/block-height/171757
http://blockchain.info/block-height/171759
http://blockchain.info/block-height/171760
http://blockchain.info/block-height/171763

Interestingly, the timestamps on their two consecutive blocks 171759 (2012-03-18 19:31:32) and 171760 (2012-03-18 19:31:30) are out of order! This implies to me that either there are some shenanigans I don't understand the point of, or this is a botnet without good clock sync.

Can someone explain what the timestamp field is used for?

ps: someone who isn't limited to the newbie forum, please copy+paste this post to the myster miner thread. edit: thanks, Mushoz!
