Are you running that code via the location bar?
You can no longer run JavaScript code via the location bar in Firefox 6 and later.
You can see an error message in the Tools > Error Console.
That code now gets a null principal for security reasons and doesn't have any effect (Bug 656433).
You need to create a (keyword) bookmarklet and run the code by invoking that bookmark.
NoScript can allow you to run such code via the location bar, see:

Thanks for the guidance. When I couldn't find the "add bookmark" option, I took one of my old, unused bookmarks and severely modified its properties. Now when I enter its keyword into the location area up pops the date and time I wanted. But for the several web pages I've looked at, the date and time is always the present date and time. another problem.
A lot of websites are generated dynamically by a script (e.g. PHP or other server side script) that runs on the server and in that case you will always see the current date.
Thanks, again. I suspected something like that. Regards, ES
