title: Is python uuid1 sequential as timestamps?
body: <p>Python <a href="http://docs.python.org/library/uuid.html" rel="noreferrer">docs</a> states that uuid1 uses current time to form the uuid value. But I could not find a reference that ensures UUID1 is sequential.</p>
  
  <pre><code>&gt;&gt;&gt; import uuid
  &gt;&gt;&gt; u1 = uuid.uuid1()
  &gt;&gt;&gt; u2 = uuid.uuid1()
  &gt;&gt;&gt; u1 &lt; u2
  True
  &gt;&gt;&gt; 
  </code></pre>
