Developer Tools - UUID, Time & Password

Generate identifiers, check times, and handle small values that show up while debugging. UUIDs and passwords are created locally. Timestamps and time zones read log lines or a JWT exp. Hashes, ASCII, doubles, and IP lookup sit in the same set. Nothing you type is uploaded.
