| 27 |

| 28 |
* 1. Gregorian time UUID |
| 29 |
* 2. DCE security UUID |
| 30 |
* 3. Name-based UUID hashed with MD5 |

* 6. Reordered Gregorian time UUID |
| 34 |
* 7. Unix Epoch time UUID |
| 35 |
* 8. Custom format UUID |
| 36 |
* |

* This returns `null` if the UUID is not an RFC 9562 (formerly RFC 4122) variant, since the version is only |
| 38 |
* meaningful for this variant. |
