If the epoch in this proposal were changed to something closer to the present day (2000-01-01 or the UNIX epoch) the format could easily recover some bits from the time fields to put in the PRNG-generated "node" fields. I wonder why they chose the Gregorian epoch?
- pjscott 5y agoThe Gregorian epoch was chosen for UUID v6 in order to make it as similar to v1 as possible, for ease of updating existing software. There are two more types of UUID proposed in this draft RFC: v7 which uses the Unix epoch and allows more time precision, and v8 which can use any monotonic timestamp source.
