'str' object has no attribute 'strftime' in ofxprinter

[aforch]

I'm encountering an issue when attempting to utilize the ofxprinter write function. The error info is below:

Traceback (most recent call last):

The printDate method of an OfxPrinter object should be called with a first parameter dt.

dt should be a datetime object which does have a strftime method. Looks like in this case the printDate method was called with dt being a string instead of a datetime.
