Summary: os.stat() subsecond file mode time is incorrect on Windows

Initial Comment:
Either the new ability of os.stat() to report subsecond
file modification times, or the os.utime() function,
appears to have a bug on Windows. The following script
illustrates. The problem is that the decimal part of
the modification time reported by os.stat() is always
equal to the decimal part of what was passed to
os.utime() divided by ten (and rounded).

###Begin Script
import os

strPath = "c:/test.xxx"

#Create the file
f = open(strPath, 'w')
f.close()

#Set the file mod time
t1 = 1159195039.2
os.utime(strPath, (t1, t1))

#Get the file mod time
t2 = os.stat(strPath).st_mtime

print t1, t2

###Sample output
1159195039.2 1159195039.02

Sorry, although it can be inferred from the report, I should
mention that this is with Python 2.5.
