	What did you expect? Object methods bind tighter than operators so
what you have is the equivalent of

dn = datetime.datetime.now()
dd = datetime.timedelta(hours=2).strftime(...)
date = dn + dd

	Try

>>> import datetime
>>> date = datetime.datetime.now()+datetime.timedelta(hours=2).strftime( '%y-%m-%d %H:%M:%S')
Traceback (most recent call last):
  File "<interactive input>", line 1, in <module>
AttributeError: 'datetime.timedelta' object has no attribute 'strftime'
>>> date = (datetime.datetime.now()+datetime.timedelta(hours=2) ).strftime( '%y-%m-%d %H:%M:%S')
>>> date
'12-09-16 03:50:44'
>>> 

	Note the ( ) wrapping the the + clause, with strftime() applied to
the result of that...
