While document.lastModified is indeed a DOM thing, it doesn't seem 
unreasonable that Zope's property of similar name be available. I don't 
know where a browser would be expected to get that from specifically, 
though no doubt it's some HTTP header. A very-quick Mozilla search 
indicates it might be 'last-modified' in the response:

http://lxr.mozilla.org/seamonkey/source/content/html/document/src/nsHTMLDocument.cpp#789

So try RESPONSE.setHeader('last-modified', some_time) with the document 
you're running your Javascript on and see what that does for you.

I can't watch HTTP conversations right now, but if Zope doesn't try 
this, I think it probably should, and if it does, but it doesn't work, 
it should definitely be fixed. Consider filing a Collector issue in 
either case. (A quick Zope source search shows no instance of 
last-modified in ZPublisher.)

Also, if you post the appropriate code fragments, others can test more 
easily to see if this is a problem with your setup or in general.
