I made a comparison list with the most known uuids out there, a couple of days ago, it was quite fun discovering all the different kinds of uid and their pros/cons.
what's the resolution on those? 32 bits, 100 years.. that seconds right? doesn't sound excellent for time ordering. 100 years also seems a little short but at least I'll be dead
