I don't feel strongly on this, but it does strike me as odd that a function
intended to avoid culturally-sensitive output would use an English phrase.
I'd lean towards IE/Opera, using notation from ECMAScript that is equally
cryptic to all cultures :-)  At least that would be consistent with
Number.toString() and would reinforce the fact that there are other methods
to produce strings in the user's locale.

Are there English phrases specified anywhere else for output?

Currently, implementations are inconsistent about what they produce for
(new Date(NaN).toString()).
IE and Opera produce "NaN", while FF and Safari produce "Invalid Date".

Since toISOString is a new function, we have the opportunity to specify
what we want the result to be.

Does anybody have an opinion. It could be either "NaN" or "Invalid Date" or
something else. "Invalid Date" has the advantage that it is more end-user
meaningful if it actually leaks through to be visible on a web page
(although that is a pretty Anglo-centric perspective).

Unless, I here strong opinions otherwise I think I'll go with "Invalid
Date".
