UUIDv7 library and demo

[Thaddy]

I have written a small, cross-platform, fully rfc compliant implementation for the UUIDv7 time sortable UUID format. This is an increasingly important UUID format and used in many distributed database applications. E.g. Amazon and PostGreSQL support it through TLE's

Includes a demo and a library with lots of documentation.
Example output:

Code: [Select]

Original time: 2025-04-28 09:25:25.303
Generated UUID: {01967BB7-30B8-747A-9F53-08EBCA9659CD}
Is valid UUIDv7?: TRUE
Extracted time: 2025-04-28 09:25:25.304
Difference (ms): 1

Generated UUID: {01967BB7-30B9-706F-B8F9-C8716A81A18A}
Is valid UUIDv7?: TRUE
Extracted time: 2025-04-28 09:25:25.305
Difference (ms): 2

Generated UUID: {01967BB7-30BA-7861-9532-AFB1574F628F}
Is valid UUIDv7?: TRUE
Extracted time: 2025-04-28 09:25:25.306
Difference (ms): 3
Note this is much smaller and validates better than some other code.

Hi Thaddy
Cool, but where is it?!?

Sorry my bad flew right over the bottom...

The attachment disappeared, corrected.
I wrote it mainly because all other implementations were frustratingly over-complex and did not always validate so I reduced all handling you need to less than a 100 lines of code that does always validate.
