https://bitcointalk.org/index.php?topic=37743.0A long time ago I did a quick survey of Satoshi's posts just for fun and found that he seemed to be posting with a US time zone.
Here is the graph (X axis are hours, Y axis is posts, times are GMT):

And the data itself:
[[0,32],[1,23],[2,15],[3,10],[4,9],[5,3],[6,3],[7,0],[8,0],[9,1],[10,0],[11,0],[12,3],[13,5],[14,14],[15,18],[16,46],[17,65],[18,65],[19,43],[20,42],[21,55],[22,46],[23,42]]
As you can see the night dip is between 6-11am GMT, so assuming this person sleeps at night, he should live in GMT-5 to GMT-7 somewhere which is the Americas.
Anyway, this was just a quick fun thing I did way back when. The reason I'm posting it now is that somebody dug up my IRC logs where I promised that I'd post it on the forums.

Stefan Thomas did a symilar experiment in 2011 and concluded that if Satoshi Nakamoto is a single individual with conventional sleeping habits, it suggests he resided in a region using the UTC−05:00 or UTC−06:00 time offset. This includes the parts of North America that fall within the Eastern Time Zone and Central Time Zone, as well as parts of Central America, the Caribbean and South America. It is a large and populated area.
It also gives some credibility to the theory that Hal Finney was Satoshi. I've just been researching
Satoshi and stumbled onto your post.
Satoshi was also a very careful person that was very concerned about privacy so he may have deliberately posted between certain times or if he was from Japan it wouldn't have been unusual for him to be working throughout the weekends. The times he didn't post
could also indicate he was working at that time. Perhaps as a University lecturer.
After his first post, in which he used American spelling, he switched to English spelling for all the rest.
I think you proved Theymos rarely sleeps.

Let suppose these two things
- He was human, not a bot not an alien
Are you sure ?

Who is Satoshi Nakamoto ? Suspects, frauds and conspiracies.
