The documentation in the Elisp manual for `file-attributes' and for
file-modification undo-list elements hasn't been updated to match the new
high-precision timestamp format.
Patch attached.

That's normal at this stage: documentation usually gets updated only
late in the release process, which didn't start yet. There are
markings in etc/NEWS that tell which changes are not documented yet.

Thanks.

The file-attributes entry is marked with "---", so it's good that we
have this report.

Ah, I didn't realise that's how things worked. I'll know for next
time. Thanks!

Glad it's still useful for something. I suspect the changes to the undo
entry format also risked being overlooked too, since they aren't
mentioned explicitly in that etc/NEWS entry.

Then _that_ is a bug.

Thanks for the bug report. I installed a fix for it in
trunk bzr 110628, which you can see here:

There's still more to do.
You can use @code{file-attributes} to get a file's last modification
time as a list of two numbers. @xref{File Attributes}.
@cindex modification time of file
@item
The time of last modification as a list of two integers (as above).
@item
The time of last status change as a list of two integers (as above).
For example, here are the file attributes for @file{files.texi}:
[...]
@item (19145 42977)
was last accessed on Oct 5 2009, at 10:01:37.
etc.
