Re: Using javascript "document.lastmodified" in PHP-include

The Javascript read-only property Document.lastmodified reflects the content (if any) of the HTTP header Last-modified: associated with the document. In the header's absence, document.lastmodified has the value 0, which is represented as midnight January 1st 1970 - hence what you are seeing. There is no Last-modified: HTTP header. You *could* just emit the lastmodified date as HTML output as Andrew Braund suggests if you've no other reason for wanting doument.lastmodified to have the right value. But if you *do* need a valid value for document.lastmodified, the 'proper' fix is to ensure you send a valid HTTP Last-modified: header, e.g. header("Last-modified: date-string") with a suitable value for date-string, perhaps derived as Andrew suggested. The usual warnings about using header() before sending HTML output apply. David.
