    https://docs.python.org/3.6/library/uuid.html#uuid.UUID

    uuid.uuid1(node=None, clock_seq=None)

    Generate a UUID from a host ID, sequence number, and the current time. If node is not given, getnode() is used to obtain the hardware address. If clock_seq is given, it is used as the sequence number; otherwise a random 14-bit sequence number is chosen.

    ^^

    This neglects to mention that if you call uuid1() in quick succession with no parameters, you can get a repeat uuid.

    I had a bug because of this.

    It would have been nice if the docs mentioned the fact directly.

    It's only a sentence to add, and would have saved a lot of time.

    There's now a paragraph near the top of the uuid page with some info on this:

    Depending on support from the underlying platform, uuid1() may or may not return a “safe” UUID. ...

    which was introduced by #138.
