Pre-review checklist

• I have performed a self-review of my code.
• If my PR fixes a bug or introduces a new feature, I have added thorough tests.
  - [ ] If my changes are non-trivial and do not concern a reported issue, I have added a changelog entry.

And please target branch stable, to fix this for v2.113 still, where these UUID additions landed.

TODO for next PR:

• It is need to exclude possibility of ticks overflow: add checked int and check the initial offset value
• Write a comment about user can't leave this factory on for long because the system wall clocks and monotone clocks will accumulate difference

LDC CI confirms that the unittests now pass on macOS arm64 too - the 3 hnsecs for the test, converted to ~2.9 hnsecs internally in 24 MHz MonoTime ticks, now make the sub-ms part end up correctly in the 2nd bin (about [2.5, 5) hnsecs, due to the 4096 bins per ms).
