Unix seconds: integer count of seconds since 1970-01-01 UTC. Compact & timezone-free.
Unix milliseconds: same epoch, ×1000. JavaScript's Date.now().
ISO 8601 (UTC): human-readable string ending in Z.
ISO 8601 (zoned): same instant with a numeric offset like +10:00.

All four describe the same instant. Only the wall-clock display changes.

All times below reflect the selected timezone.
