I expect you'll have to get the Python Win32 extensions (visit ActiveState's
web site), and use the SetFileTime() Win32 API function (which allows
changing all three times).

No, Win9x beasts store all three.

Windows archiving systems vary in what they do to the date stamps, and
that's a PITA.
Creation time is exactly what it sounds like <wink>. When you *copy* a file
using native Windows functions, the creation time on the copy is set to the
current time, but the modified time is inherited as-is from the original.
This drives Unix weenies insane, but it's actually quite useful in its own
strange way <wink>. Note that this implies it's quite possible on Windows
to see a file with a modification time older than its creation time --
creation does not imply modification. Of course almost none of this is
documented clearly anywhere (that I know of, anyway).
