copy-file broken

[Andre Spiegel]

When I use copy-file with the keep-time option, the resulting file is
dated 1970-01-01.  I already reported this on this list a few days ago,
but there has been no response yet.  Myself, I'm not sufficiently
familiar with fileio.c to debug this.

I'm seeing the problem under Debian GNU/Linux, 2.4.21, Emacs CVS HEAD.
The problem may be related to Ken Raeburn's change in fileio.c from
2002-07-15 (version 1.454) -- at least, that's the most recent change in
the code that seems to handle keep-time.

Would somebody who knows his way around there please have a look?
