# UUID Inspector

> Identify a UUID version and variant, and extract the timestamp from v1, v6 and v7.

A UUID inspector reads the version and variant bits to identify which of the eight UUID versions an identifier uses, validates the 8-4-4-4-12 format, and extracts the embedded creation timestamp from versions 1, 6 and 7 — the only versions that carry one.

## FAQ

### Why is UUIDv7 better for database keys?

Its first 48 bits are a Unix millisecond timestamp, so new values sort after old ones. That keeps B-tree inserts at the right-hand edge of the index instead of scattering them, which on large tables is a substantial performance difference.
