I was looking at the "old" bitcoins:  those of blocks 0, 1, 2....

I can't find any of them which has been redeemed.

So here are a simple question:

what is the oldest non-generation transaction?

PS.  Ok, found it using a small script:  http://blockexplorer.com/b/170

This means that Satoshi has been running his computer during 17 hours before he tried to make a transaction.  I guess he was testing the difficulty adjustment.
