UUID v1 Generator – Timestamp-Based (Uses Time & MAC Address)

UUID v1 is generated using the current timestamp and MAC address (a unique hardware identifier). Since it includes the MAC address, it can potentially reveal information about the system generating it. However, it provides a time-ordered sequence of UUIDs, which makes it useful for databases and logs where sorting is required. A v1 UUID consists of a timestamp, clock sequence, and node (MAC address).
