Summary: PyTime value returned from FindFilesIterator is incorrect

Initial Comment:
The PyTime value in the WIN32_FIND_DATA object returned from FindFilesIterator() is incorrect. Say fdata is an instance returned from FindFilesIterator(), then time.localtime(int(fdata[3])) returns the UTC time, not the local time.

To reproduce:
(1) Create a new text file, say C:\test.txt
(2) Observe the modification date.
(3) Run the script on the command line with the path to the file created in (1) as the argument, e.g. pytimebug.py C:\test.txt
(4) Observe local time printed on screen is incorrect; in fact it is the UTC time.

Message:
It seems the PyTime value (returned from FindFilesIterator()) is offset
from the correct value by the value of the UTC offset. E.g, if I find the
UTC offset, and subtract this from the PyTime before converting to
localtime, I get the correct result:

            utc_offset = (datetime.utcnow() -
datetime.now()).total_seconds()
            ftime = time.localtime(int(finfo[3]) - utc_offset)

Now ftime is correct.
