UUID validator / version inspector

Validate UUID format, inspect version and variant, and show the embedded millisecond timestamp for UUID v7.

Input

Hyphenless, braced, and urn:uuid: forms are accepted and normalized to canonical form.

UUID v7 carries a timestamp clue

The first 48 bits of UUID v7 hold a millisecond Unix timestamp. This tool converts that field back to UTC. UUID v4 does not carry the same time field.
