Version 1 UUID

Version 1 UUIDs are time-based. They leverage a timestamp, usually representing the date and time the UUID was generated, to ensure uniqueness. This timestamp is combined with the node, which is typically a MAC address of the generating machine. While this method ensures that UUIDs are unique and easily sortable by time, it does reveal some potentially sensitive information, like the generation time and the generating machine's identity. Despite this, it's useful in distributed systems where knowing the creation time of an object is beneficial. For example, in databases, it helps in organizing entries in the order they were created.
