.. function:: uuid1(node=None, clock_seq=None)

Generate a UUID from a host ID, sequence number, and the current time. If *node*
is not given, :func:`getnode` is used to obtain the hardware address. If
*clock_seq* is given, it is used as the sequence number; otherwise a random
Generate a UUID from a host ID, sequence number, and the current time
according to :rfc:`RFC 9562, §5.1 <9562#section-5.1>`.

When *node* is not specified, :func:`getnode` is used to obtain the hardware
address as a 48-bit positive integer. When a sequence number *clock_seq* is
not specified, a pseudo-random 14-bit positive integer is generated.
14-bit sequence number is chosen.


.. function:: uuid3(namespace, name)

Generate a UUID based on the MD5 hash of a namespace identifier (which is a
UUID) and a name (which is a :class:`bytes` object or a string
that will be encoded using UTF-8).

This is an alternative to :func:`uuid1` to improve database locality.
