Extra ) after lastModified.

One should add that the result will look somewhat silly in Safari
3.0.4,
the current Windows beta (empty string); and that lastModified is a
misnomer because in practice it means "last uploaded to the server".

It is not a misnomer. It reflects the date the document you are viewing
was last modified. It has nothing to do with "uploading". The FAQ
index.html, while I have been editing the FAQ, has *never* been
uploaded. The date that document.lastModified gives is exactly that,
the date that the document was last Modified. Whether that modification
is by uploading a replacement, direct editing on the server, or by
being generated on the server.


Your lack of insight is most impressive.

When a document is, for whatever reason, re-uploaded to a server
(perhaps because of a change of server, for instance), it gets a new
Last-Modified header. But if the content of the document, as seen by
the user, is unchanged, it is a disservice to assert that there has been
a modification. It is also a disservice if the change is too slight to
matter to the reader, for example correcting non-misleading typos.[*]

Please remember what WSC is alleged to have said about Americans (and if
possible provide an authoritative reference); in this respect, the task
is as yet incomplete.



ASIDE : I now have an improved Leading Zero function, LZ; it is the
fastest (in IE6) of three which all, AFAICS, always give the right
answer. See <js-tests.htm#LZ>.

function LZ(x) { return (x!=null&&x<10&&x>=0?"0":"") + x }
