The values from os.stat() is really poorly documented

   http://www.python.org/doc/lib/os-file-dir.html#l2h-968

, but I agree that the returning values which is different from cpython
is unfortunate. But what to do?

I'm sure most unix users feel fine with a simple "int(mtime / 1000)"
hack, because the file time resolution is a second on (all?) unices. On
WinNT this would be an actual loss of information since WinNT have
millisecond file time resolution.

How about returning "mtime / 1000.0" as a float number. This is already
the case for CPython on macs. If any libraries fail to handle a float it
is surely a bug in the library.

Comments?
