Is python uuid1 sequential as timestamps?

Question

Python docs states that uuid1 uses current time to form the uuid value. But I could not find a reference that ensures UUID1 is sequential.

>>> impor         


        

Answer 1

But not always:

>>> def test(n):
...     old = uuid.uuid1()
...     print old
...     for x in range(n):
...             new = uuid.uuid1()
...             if old >= new:
...                     print "OOops"
...                     break
...             old = new
...     print new
>>> test(1000000)
