Interesting, they have their own custom epoch, the "twepoch":

    // Tue, 21 Mar 2006 20:50:14.000 GMT
    val twepoch = 1142974214000L

According to the README they can fit 69 years worth of timestamps in 41 bits with the custom epoch, since they don't care about any times that happened before Twitter launched.

That's the time of the first tweet. It saves us 30-something years of id space.

Totally OT but do you guys still know the content of the first tweet?

Apparently the best google-fu effort only yields #20: http://twitter.com/jack/status/20

That is, as far as the archive goes, the very first public tweet.

Mostly, though, we think it's just adorable.
