alt Hacker NewsHow confident are you that your machines clocks are in perfect sync? What about the risk of clock drift + correction, or hardware issues?

I get why sync of mutiple machines matters for ordering and causality, but why is it a problem for uniqueness?
Not GP, but: not confident. How confident would I be to avoid a (slightly lower entropy) UUID collision while also avoiding a clock desync landing on the exact same logged millisecond? Very, which is how confident I was about not encountering an UUID collision before this thread, so very++ I guess.
