GUID / UUID v6 is a reordered time-based identifier designed to be lexicographically sortable by creation time. It is essentially v1 with the timestamp bytes reordered so that the most significant time bits come first, enabling simple string/byte comparisons for time-based sorting. This makes v6 ideal for database indexing and systems requiring time-ordered keys.
