Just a stupid question, but why not append the date, even in seconds as hex. It's just a few bytes and would guarantee that everything OK now will be OK in the future?

You can just use a different UUID variant which includes timestamp data instead (e.g. v1 or v7), there are also variants which include the MAC address.

And use uuid v5 to hash it :)

yeah, any sort of additional semi-random data could've helped prevent this, I'm sure. That, however, is also kind of the idea of UUIDv4, it has lots of randomness and time built in already.

UUID v4 consists of only random bits, no timestamp info.

		oh, interesting, I didn't know that and this could possibly be part of the problem perhaps depending on what's used as the seed.
