UUID v1 Generator

Generate time-based Version 1 UUIDs for unique identification within a specific timeframe.

In-Depth Guide

Everything you need to know

A UUID Version 1 is generated from a time and a node ID (usually the MAC address). Unlike Version 4 which is random, Version 1 is deterministic based on when and where it was created.

Key Characteristics:

Time-Ordered: Successive UUIDs generated on the same machine are monotonic, making them useful for sorting in databases.
Uniqueness: Guaranteed unique across space and time due to the combination of clock-seq and node ID.
Privacy Note: v1 UUIDs leak the time of generation and the MAC address of the generator. Use v4 for anonymous identifiers.
