Decorate a unittest method with this function to cause the value

increase by one each time it is called. This ensures things like
last modified dates always increase.
We make three guarantees about the value of :func:`time.time`
returned while the decorated function is running:
1. It is always *at least* the value of the *real*
:func:`time.time`;
2. Each call returns a value greater than the previous call;
3. Those two constraints hold across different invocations of
functions decorated. This decorator can be applied to a
method in a test case::

It can also be applied to a bare function taking any number of
