So long as your pandas version is 0.15 or higher then the following would work assuming your dtype is already a datetime:

In [167]:

df[df.System_created.dt.day == 5]
Out[167]:
       Qty      System_created  Total
index                                
5        2 2014-11-05 11:15:47  21.76
6        1 2014-11-05 11:15:48   3.32

So basically the dt attribute allows you to access the components of your datetime to perform the comparisons you desire for filtering
