mocker doesn't seem to work with utcnow

[John O'Brien]

Based on the documentation, it seems that this should work. However it does not.

In [4]: obj = mymocker.replace("datetime.datetime.utcnow")
In [5]: obj()
Out[5]: <mocker.Mock object at 0x2558c90>
In [6]: mymocker.result(123)
In [7]: mymocker.replay()
In [8]: from datetime import datetime
In [9]: datetime.utcnow()
Out[9]: datetime.datetime(2009, 2, 21, 13, 23, 55, 216273)

datetime is implemented in C, so this won't work indeed.
