Summary: shutil.copy2 modifies decimal part of last modification time

Initial Comment:
Problem on Windows 2000 with Python 2.5.

When copying a file with shutil.copy2,
the last modification times should be copied.

What happens is that :
+ the integer part is copied correctly
+ the decimal part is modified 

+ some samples :
           source-lastmod-time   copy-lastmod-time
  file_0.txt 1172574881.34375 => 1172574881.034375
  file_1.txt 1172574881.46875 => 1172574881.046875

+ what is really odd is that the decimal part is
  divided by 10

The attached file *test_shutil_copy2.py* contains an Unit Test that demonstrate the incorrect behaviour
